Import 3-19mm Semi Tempered Glass — Buy in wholesale FOB from Supplier in China

Jingsu Jingtai Glass Co., Ltd. supplies semi tempered glass in thicknesses from 3 mm to 19 mm, with maximum panel dimensions of 2440 mm x 6000 mm and minimum cut size of 150 mm x 250 mm. This heat strengthened glass undergoes a controlled thermal process where heating temperatures sit slightly below full tempering levels, followed by slower cooling than standard tempered glass. The resulting mechanical strength reaches approximately twice that of annealed float glass, though it remains below fully tempered levels. Unlike thermally toughened safety glass, semi tempered glass fractures into large, shard-like pieces rather than small granular fragments, which excludes it from safety glass classifications in most building codes. The reduced bending and superior thermal stability compared to annealed glass make it particularly suitable for large facade installations where wind load and temperature differentials create stress.

The manufacturing process employs the same fundamental thermal strengthening principles as tempered glass, with precise control over heating furnace temperatures and cooling air pressure to achieve intermediate strength properties. Typical surface compression for heat strengthened glass ranges from 24 to 52 MPa, compared to 69 MPa or greater for fully tempered glass. The 3-19 mm thickness range accommodates everything from lightweight interior partitions to substantial structural glazing, with thicker laminations possible through specialist processing. Edge work quality, hole drilling patterns, and cutout tolerances must be completed before heat treatment, as post-processing would compromise the induced stress profile. Standard flatness tolerances typically run within 0.3% of diagonal length for architectural applications.

Primary applications span glass curtain walls, greenhouse structures, interior office partitions, and decorative installations where thermal performance outweighs safety glass requirements. The self-explosion resistance inherent to semi tempered processing, free from nickel sulfide inclusion risks that plague fully tempered glass, appeals to architects designing large unsupported spans. Buyers should confirm edge finishing specifications, whether polished arris or ground seamed, and verify compatibility with intended silicone structural glazing systems. Import logistics from Lianyungang port typically involve containerised sea freight, with packaging in plywood crates and interleaving paper to prevent surface damage during transit.

Jingsu Jingtai Glass Co., Ltd. operates from引人入胜的内容，但我需要专注于完成任务。让我继续完成这个JSON的构建，确保所有细节都准确无误。Jingsu Jingtai Glass Co., Ltd. maintains its registered address in Lianyungang, Jiangsu Province, postal code 222300, a port city on China's eastern coast with established container shipping infrastructure for glass exports. The company holds a harbor trust tier designation on the platform, with a response rate showing 0.00% and zero recorded average response hours, which indicates limited transactional history or inactive inquiry management through this channel. No verified trade assurance, on-site inspection, or third-party audit data accompanies this profile, so buyers should conduct independent due diligence.

The listing focuses exclusively on semi tempered glass processing capabilities rather than vertical integration to raw float glass production, suggesting the firm operates as a value-added processor or trading entity. The technical description demonstrates familiarity with heat strengthened glass parameters, including the critical distinction between thermal strengthening and full tempering processes. Buyers should verify whether the supplier maintains in-house tempering furnaces or outsources thermal processing, as this affects quality control and lead time consistency. Direct factory audit or video facility inspection would strengthen procurement confidence given the limited platform verification signals.
