Guangdong Tengbo Glass Technology Co., Ltd. is a professional tempered glass manufacturer dedicated to producing safety glass for architecture, furniture, appliances, and industrial applications. Built on years of hands-on processing experience, the company has grown into an export-oriented supplier serving distributors, contractors, brands, and project owners across multiple continents. Tempered glass has become a trusted choice among designers and engineers because it delivers exceptional strength, dependable safety performance, and a long service life under demanding conditions. When ordinary annealed glass breaks, it forms large, sharp shards that can cause serious injury, while tempered glass fractures into small, blunt granules that greatly reduce the risk of harm. That single safety characteristic, combined with the material's ability to withstand thermal stress and mechanical impact, explains why tempered glass is now specified in everything from shower enclosures to high-rise facades. At Tengbo, our expertise lies in converting these material advantages into reliable, repeatable tempered glass solutions that meet the technical and commercial expectations of buyers worldwide. From the first inquiry to the final shipment, our team focuses on consistency, customization, and clear communication so that every client receives glass that fits the project precisely, and you can explore our full capabilities on the Home page.

Tempered glass, often called toughened glass, is a type of safety glass produced through a controlled thermal process that permanently alters the internal stress pattern of the material. The manufacturing sequence begins with careful cutting, edge grinding, and drilling of the raw float glass to the required dimensions and shape. Next, the glass travels through a roller hearth furnace where it is heated to approximately 620–700 °C, a temperature high enough to soften the surface but not high enough to deform the sheet. Immediately after heating, the glass passes into a quenching section where high-pressure air jets cool both surfaces rapidly and evenly. This rapid cooling solidifies the outer surfaces first while the inner core remains hot, and the subsequent contraction of the core places the surface layer into permanent compression. The resulting compressive stress on the surface and tensile stress in the center give tempered glass a bending strength roughly four to five times greater than that of ordinary annealed glass. Because the process is irreversible, any cutting, drilling, or edge modification must be completed before tempering, which is why precise pre-processing drawings matter so much in projects that involve drilling tempered glass.

The most valued properties of tempered glass include high mechanical strength, predictable breakage behavior, moderate thermal shock resistance, and good surface durability. Its surface compression typically exceeds 90 MPa, which allows thinner sheets to carry loads that would require much thicker annealed glass. Thermal resistance is another clear benefit, since tempered glass can usually tolerate temperature differences of roughly 150–200 °C between the center and the edge without failing. Scratch resistance is improved by the compressive surface layer, which helps the glass resist minor abrasion during handling, cleaning, and daily use. It is worth noting that heat strengthened glass occupies a middle ground between annealed and fully tempered products, offering strength roughly twice that of annealed glass while breaking into larger, more angular pieces. Specifiers choose between these two products depending on wind load, safety requirements, and the acceptable breakage pattern for a given location, and a competent tempered glass manufacturer will always advise on the right option.

Tempered glass is used in architecture for doors, windows, partitions, balustrades, and curtain wall panels where safety glazing is mandatory. In furniture manufacturing, it appears as table tops, shelving, cabinet doors, and display surfaces that must resist impact and heat. Home appliances and electronics rely on tempered glass for control panels, oven doors, touch screens, and display covers that demand dimensional accuracy and optical clarity. The automotive and transport sectors use tempered glass for side windows, rear windows, and interior partitions, while industrial equipment uses it for machine guards, sight windows, and protective covers. Curved tempered glass extends these possibilities to rounded facades, cylindrical showcases, and designer furniture shapes that flat glass cannot achieve. Each application imposes its own requirements for thickness, edge finish, and tolerances, so understanding the end use is the first step in specifying the right product.

Guangdong Tengbo Glass Technology Co., Ltd. combines advanced production equipment with mature tempered glass processing technology, allowing us to handle both standard orders and complex customized projects. Our lines are equipped for precise cutting, CNC shape processing, edge polishing, drilling, and controlled tempering, which means a single supplier can deliver a finished part rather than a semi-finished sheet. Strict quality control runs from raw material inspection through process monitoring, impact testing, and final dimensional checks, so every batch is verified before packing. Customization is a core strength: we produce sizes, shapes, edge treatments, holes, cutouts, thicknesses, and finishes according to customer drawings and samples. Where applicable, our products are manufactured to comply with recognized industry standards, and we support buyers who need documentation for their own certification or project approval processes. Competitive pricing, fast lead times, stable supply capacity, and solid export experience make us a dependable partner for long-term programs, and you can learn more about our factory, milestones, and team on the About Us page.

Choosing the right tempered glass manufacturer is not only about price; it is about risk management, schedule reliability, and repeatable quality across repeated shipments. A supplier that understands glass processing can catch design problems early, such as holes placed too close to the edge or cutouts that create stress concentrations that lead to cracked tempered glass later. Tengbo reviews drawings before production and communicates clearly when a modification would improve yield or safety. We also maintain sufficient raw glass inventory and tempering capacity to keep production schedules stable during peak seasons. For buyers who order frequently, this combination of technical advice and dependable output reduces both cost and administrative effort. The result is a supply relationship that supports your product quality instead of creating problems for your assembly line or installation team.

Our standard offering covers clear tempered glass, tinted, frosted, patterned, low-iron, coated, and laminated-tempered combinations, giving designers a wide palette of optical and performance options. Thickness options range from thin gauges used in appliances and displays to heavy sheets used in structural glazing, floors, and stair treads. Maximum producible sizes depend on thickness and glass type, and our sales engineers confirm feasibility before quoting so that expectations are aligned from the start. Edgework includes flat polish, pencil edge, bevel, drilled holes, and cutouts, all performed to controlled tolerances that fit the final assembly. Packaging and safe delivery are treated as part of the product: glass is separated by interleaved paper or film, protected with corner guards, and packed in export-grade wooden crates for domestic and international markets. You can browse the complete range on our Product page.

In building and construction, our tempered glass is used for entrance doors, shopfronts, interior partitions, stair railings, balcony balustrades, and facade elements that must satisfy safety glazing requirements. For home and commercial furniture, we supply table tops, shelf panels, showcase covers, and cabinet doors that combine durability with a clean, premium appearance. Home appliances and electronics customers use our glass for oven doors, control panels, touch interfaces, and display covers where flatness and edge quality directly affect assembly and appearance. Specialty projects cover custom architectural glass, industrial machine guards, and interior design features that require unusual shapes or combined processing. Because project conditions vary widely, we work closely with each customer to match thickness, finish, and edge treatment to the actual load and environment. The result is a product that performs correctly for its intended use rather than simply meeting a nominal specification.

Guangdong Tengbo Glass Technology Co., Ltd. supports OEM and ODM projects from drawing review and sample development through mass production and export documentation. Customers can send CAD drawings, PDF specifications, or physical samples, and our technical team responds with feasibility feedback, tolerance confirmation, and a clear quotation. Multilingual communication and responsive after-sales support help overseas buyers resolve questions quickly, even across different time zones. We work as a partnership-oriented supplier for distributors, contractors, brands, and project owners, which means we plan capacity around your forecast rather than treating each order as an isolated transaction. For customized requirements such as drilling tempered glass panels for specialized hardware, unusual shapes, or branded finishes, detailed review at the sample stage prevents costly issues later in production. More information about tailored services is available on the Customized page.

Quality assurance begins with incoming material inspection, where glass thickness, flatness, and visual defects are checked against specification. During processing, our teams monitor dimensions, edge quality, hole positions, and cleaning quality before the glass enters the tempering furnace. After tempering, we evaluate fragmentation behavior, impact resistance, thermal stability, flatness, and overall visual appearance before any item is approved for packing. Fragmentation testing confirms that the glass breaks into small, relatively uniform granules, which is the fundamental safety criterion for tempered glass. Flatness and optical checks matter for laminated or coated assemblies, where distortion and reflection problems are easier to prevent than to correct. Traceability systems link finished pieces back to production batches, so consistent batch quality can be maintained and any deviation investigated thoroughly.

Ordering starts with sharing your specifications, drawings, quantity, and application requirements so that we can evaluate feasibility and propose the most suitable construction. Our team then prepares a quotation covering glass type, thickness, processing, packaging, and lead time, along with any technical notes that affect the design. Sample confirmation is a recommended step for new projects, since it allows you to verify dimensions, edge appearance, and finish before committing to full production. Once confirmed, we issue a production schedule and a shipping plan that aligns with your installation or assembly timeline. Quality inspection reports and photographs are provided before shipment, and we remain available for after-sales support once the goods arrive. To keep things efficient, please include the following details in your inquiry:

Tempered glass is glass that has been heated to around 620–700 °C and then rapidly cooled, which creates permanent compressive stress on its surfaces. This treatment makes it roughly four to five times stronger than annealed glass and changes its breakage pattern. Instead of long, sharp shards, tempered glass fractures into small, blunt granules, which significantly reduces the risk of serious injury.

The minimum order quantity depends on glass type, thickness, processing complexity, and packing method, because set-up costs vary considerably between simple cut panels and fully processed parts. For standard products, small trial orders are often possible, while customized items are more economical in larger volumes. We recommend sending your specification so we can propose a practical minimum order and pricing structure.

Yes, we manufacture custom sizes, shapes, and edge treatments based on customer drawings or samples. Holes, slots, and cutouts are processed before tempering, since tempered glass cannot be cut or drilled afterwards without shattering. Early drawing review helps us confirm that hole positions and edge distances meet safe processing limits.

Heat strengthened glass is cooled more slowly than tempered glass, so it develops lower surface compression and roughly twice the strength of annealed glass. It also breaks into larger, more angular fragments rather than the small granules typical of fully tempered products. The right choice depends on load requirements, safety standards, and the acceptable breakage pattern for the application.

Standard production typically takes several working days after drawing and sample confirmation, while complex customized orders require additional processing time. Delivery depends on destination, shipping method, and customs clearance requirements. We provide a clear production schedule and shipping plan at the quotation stage so that you can plan installation or assembly accordingly.

Where applicable, our tempered glass is produced to comply with recognized industry standards, and supporting documentation can be provided for project approval. Every batch undergoes inspection for dimensions, flatness, edge quality, and fragmentation behavior. Inspection records are retained so that quality can be traced back to the production batch if needed.

Glass is separated with interleaved paper or protective film, then fitted with corner guards before being placed into export-grade wooden crates. Crates are designed to minimize movement and reduce the risk of edge damage during handling and transit. Special packaging requirements for long-distance or multi-modal shipments can be arranged on request.

Yes, curved tempered glass can be produced for facades, showcases, furniture, and interior features where a bent profile is required. Curvature is formed before tempering, and the geometry must be confirmed at the drawing stage because radius, thickness, and size all affect feasibility. Early technical review helps avoid problems with fitting and installation on site.

Most cracked tempered glass results from edge damage during handling or installation, stress concentrations around poorly positioned holes and cutouts, or thermal shock in certain applications. Nickel sulfide inclusions can also cause spontaneous breakage in rare cases. Proper edge protection, correct hardware design, and careful installation practice greatly reduce these risks.

We support OEM and ODM projects and accept CAD drawings, PDF specifications, and physical samples for evaluation. Our team provides feasibility feedback, tolerance confirmation, and a detailed quotation based on your requirements. Sample confirmation before mass production helps ensure that the finished product matches your expectations.
