Import Curved Tempered Glass — Buy in Bulk from Supplier in China

Curved tempered glass from Qingdao Pioneer Glass Co., Ltd is manufactured by heating flat glass to approximately 620°C and then rapidly cooling it with air jets while shaped over a mold, inducing surface compression for increased strength. The product is available in thicknesses ranging from 5mm to 12mm, with curvature radii typically between 800mm and 3000mm, as specified by customer requirements. All units undergo thermal tempering per EN 12150-1 and ANSI Z97.1 standards, ensuring fracture into small, blunt fragments rather than sharp shards.

The base material is clear float glass, with optional low-iron variants available for improved optical clarity. Surface flatness tolerance is typically ±1.5mm per meter, and edge finish options include seamed, polished, or ground. The glass can be produced with integrated coatings such as solar control or low-E, though these require separate processing and confirmation. Typical minimum order quantities are not stated, but batch production is standard for custom shapes and sizes.

This product is commonly specified for architectural facades, elevator enclosures, shower enclosures, and retail display units where safety and aesthetic curvature are required. Buyers include commercial builders, interior designers, and glass fabricators sourcing for high-end residential and public projects. Trade terms are typically FOB Qingdao Port, with packaging in wooden crates lined with foam and paper separators. Lead times vary by order complexity but generally range from 15 to 25 days after confirmation of dimensions and curvature.

Qingdao Pioneer Glass Co., Ltd operates as an integrated glass processor based in Qingdao, Shandong Province, China. The company lists laminated glass, tempered glass, insulating glass, mirrors, and decorative safety glass among its core product lines. Its supplier profile indicates a harbor-tier trust rating but provides no verified certifications, production capacity figures, or client references. The response rate and average response time are not recorded, suggesting limited active engagement on the platform.

The company describes itself as specializing in custom glass fabrication but does not claim ISO certification, in-house R&D, or export history. No information is provided about workforce size, years in operation, or factory audits. Buyers should treat this supplier as a fabricator with capability in standard curved tempered glass production but must independently verify technical compliance and quality control processes before placing orders.
