About Beijing Northtech Glass Co., Ltd. - Tempered Glass Supplier in China

China‑based Beijing Northtech Glass Co., Ltd. lists 31 active products across a spectrum of architectural glass solutions. The catalogue includes insulated glass units, laminated and float glass, low‑E double glazing, curved and oversized panels, as well as related systems such as balcony railings, curtain walls and decorative art glass. Each entry is grouped under HS chapter 70 families for flat glass, insulated units and safety glass, reflecting the standard customs classification for the sector.

The supplier’s product list further details specialty items such as heat‑strengthened glass, smart PDLC glass, ceramic frit glass, laquered glass and one‑way mirrors. In addition to flat sheet formats, the catalogue mentions structural systems like glass balcony railing, balustrade and railings, and custom services for bent or curved glass windows. All items are presented without reference to specific certifications or performance grades, focusing on the variety of glass types offered.

Product Range and Specialties of Beijing Northtech Glass Co., Ltd.

The catalogue covers core glass categories: tempered glass for building applications, laminated safety glass, float glass sheets, low‑E insulated units and specialty smart glass. In the industry, tempered glass is typically produced to meet EN 12150 or ASTM C1048, with thicknesses from 4 mm to 12 mm and a post‑tempering strength increase of at least 4 times the annealed state. Laminated glass usually complies with EN 146 or ASTM C1172, combining two or more glass plies with a PVB interlayer for impact resistance and acoustic performance. Low‑E insulated units are commonly specified with U‑values between 0.8 and 1.2 W/m²·K and solar heat gain coefficients (SHGC) of 0.25‑0.45, depending on the coating grade.

Beyond flat sheets, the supplier lists curved glass walls, oversized float panels, and decorative art glass, which in global trade are often supplied in 3‑mm to 30‑mm thicknesses and require edge polishing or tempering per project specs. Curtain wall systems and balcony railing assemblies typically integrate aluminum extrusions, glass clamps and silicone sealants, conforming to standards such as EN 1991‑1‑4 for wind load and EN 1999‑1‑1 for aluminium structures.

Trade and Export Information - Beijing Northtech Glass Co., Ltd.

Chinese glass exporters generally ship to markets in the Middle East, Southeast Asia, Europe and North America, where demand for high‑rise construction, automotive glazing and renewable‑energy façades drives imports. HS codes in the 7001‑7019 range cover flat glass, safety‑laminated units and insulated panels, and customs authorities often request test certificates that confirm compliance with safety (EN 12150/146) and thermal performance (EN 1279) standards. Typical export logistics involve loading glass sheets on wooden pallets with edge protection, then containerising in 20‑ft or 40‑ft containers; larger curved or oversized panels may require flat‑rack trucks or break‑bulk handling.

Buyers commonly request CE marking for EU shipments, ISO 9001 quality management certification, and third‑party test reports such as ISO 10545‑2 (thermal shock) or ISO 9050 (optical properties). Chinese manufacturers frequently work with freight forwarders familiar with the need for climate‑controlled storage and careful handling to avoid breakage, and Incoterms such as FOB Shanghai or CIF Dubai are standard for glass cargo.

Sourcing from Beijing Northtech Glass Co., Ltd. - Buyer Guidance

When sourcing glass from this supplier, buyers should obtain a product data sheet that specifies thickness, nominal dimensions, thermal U‑value (for insulated units) and safety‑glass compliance (EN 12150/146). Requesting a recent laboratory test report for impact resistance, light transmission and solar heat gain will verify that the glass meets project specifications. It is also prudent to ask for a copy of any ISO 9001 certificate and, for EU destinations, a CE Declaration of Conformity before placing an order.

Verification of edge quality, surface flatness (often expressed in µm per meter) and the presence of any coatings (e.g., low‑E, frit) should be confirmed by sample or photographic evidence. For custom curved or bent glass, confirm the manufacturer’s CNC bending capability, minimum radius and lead time, as these items typically require longer production cycles and specialized packaging.

What types of glass are listed in the Beijing Northtech Glass catalogue?

The catalogue includes tempered building glass, laminated safety glass, standard float glass, low‑E insulated units, heat‑strengthened glass, smart PDLC glass, ceramic frit glass, laquered glass, one‑way mirrors and related balcony railing or curtain‑wall systems.

Are there standard specifications that buyers should expect for tempered glass?

Tempered glass supplied for construction normally conforms to EN 12150 or ASTM C1048, with thicknesses from 4 mm to 12 mm and a post‑tempering strength increase of at least four times the annealed glass. Buyers should request the heat‑tempering report and surface‑flatness data.

What documentation is typically required for insulated glass units?

Buyers usually request a product data sheet showing U‑value, solar heat gain coefficient, glass thickness, spacer material and any low‑E coating grade, plus a third‑party test report (e.g., ISO 10545‑2) and a CE Declaration of Conformity for EU markets.

How is glass packaged for international shipment?

Flat glass sheets are commonly palletised on wooden crates with edge protectors, wrapped in stretch film and loaded into 20‑ft or 40‑ft containers. Curved or oversized panels may be secured on flat‑rack trucks, then transferred to break‑bulk containers with additional cushioning.

What certifications are commonly required for Chinese glass exporters?

Typical buyer requirements include ISO 9001 quality‑management certification, CE marking for EU destinations, and product‑specific test reports such as EN 12150 for tempered glass or EN 146 for laminated glass. Buyers should request copies before finalising the purchase.

What are typical minimum order quantities and lead times for custom glass products?

Standard sheet glass often has a MOQ of one pallet (approximately 1 ton), while custom curved or smart glass may require a MOQ of 500 mm² or a minimum of one panel. Lead times range from 2‑4 weeks for standard sizes to 6‑8 weeks for custom‑shaped or coated units.

Can I obtain samples before placing a large order?

Suppliers usually provide small sample panels (e.g., 300 mm × 300 mm) for visual inspection and laboratory testing. Request the sample together with the relevant test certificates to confirm compliance with project specifications.

Which global regions most frequently import the types of glass listed?

Major importers include the Middle East (UAE, Saudi Arabia), Southeast Asia (Singapore, Malaysia), the European Union (Germany, UK, France) and North America (USA, Canada), where glass is used for high‑rise façades, automotive glazing and energy‑efficient building envelopes.
