Import Borosilicate Fire Resistant Glass 4.0 — Buy in Bulk from Supplier in China

The 4.0‑grade borosilicate fire‑resistant glass offered by Qinhuangdao Scinan Specialty Glass Co., Ltd. is engineered to endure extreme temperatures while limiting flame spread. It provides high transparency that allows ample daylight penetration, and its lightweight construction simplifies handling during installation. The glass can be cut to custom dimensions to match architectural specifications. International safety standards such as ISO and CE are referenced in the product documentation.

Borosilicate glass typically contains about 80 % silica and 13 % boric oxide, giving it a low thermal expansion coefficient and excellent thermal‑shock resistance. In the industry, thicknesses from 4 mm to 12 mm are common, with light transmission values around 90 % for standard thicknesses. The material’s density of 2.23 g cm⁻³, as stated for this batch, matches the usual range for borosilicate compositions. These properties make the glass suitable for environments where rapid temperature changes occur.

Typical applications include fire‑rated doors, windows, and partition panels in commercial, residential and industrial projects that require fire safety compliance. Importers can request flexible minimum order quantities and choose FOB or CIF shipping terms, with payment options of T/T or L/C. Buyers should verify the ISO and CE certifications and confirm any custom size or processing requirements before placing an order.
