Guojian (Tianjin) Steel Co., Ltd. specializes in the research and manufacturing of non-penetrating Roof Clamps for colored steel roof panels. We offer customized corrugated profile materials, one-stop hardware component procurement, and free load-bearing test samples. Our clamps are made using a single-piece stamping process and are constructed from thickened aluminum alloy or zinc-aluminum-magnesium-carbon steel, effectively preventing the waterproof layer of the factory roof from being penetrated, thereby fundamentally eliminating the risk of roof leakage.

Guojian (Tianjin) Steel Industry specializes in the research and manufacturing of Solar Roof Hook. Our product range includes molded hooks customized according to specific tile specifications, small-scale trial production, and a complete procurement solution for entire projects. We offer two main product lines: adjustable stainless steel tile hooks and color steel plate fixtures, suitable for various roof structures, including glazed tiles, concrete tiles, and trapezoidal color steel plates.
