Guojian (Tianjin) Steel Co., Ltd. is a direct manufacturer of Triangle Bracket Connector for photovoltaic mounting systems, offering support for bulk project orders, custom hole configurations, and free sample provision. These triangular supports serve as critical reinforcement components connecting mounting posts to purlins; manufactured from high-strength Q355B steel and finished with either hot-dip galvanizing or Zinc-Aluminum-Magnesium coating, they ensure 25 years of outdoor corrosion and rust resistance. Their stable triangular design significantly enhances the mounting system's load-bearing capacity against wind and snow, and they are fully compatible with the company's complete range of C-, Z-, U-, and "Ji"-shaped steel profiles.

Guojian (Tianjin) Steel Co., Ltd. specializes in manufacturing Solar Mounting Pressing Fittings, including mid-standards and end-standards. We offer support for bulk project procurement, custom molds for non-standard module thicknesses, and third-party sample testing. The products are made from 6005-T5 aluminum alloy through an integrated extrusion process. The fixtures feature thickened anti-slip interlocking teeth and EPDM buffer pads, ensuring uniform clamping pressure and effectively preventing micro-cracks in double-layer glass component frames.

Guojian (Tianjin) Steel supplies hot-dip galvanized Round Steel Tube specifically designed for photovoltaic (PV) perimeter fencing and mounting poles. These pipes are manufactured using seamless or straight-seam national standard steel tubing that undergoes a high-temperature, full-immersion galvanizing process. Their smooth, rounded cross-section effectively disperses wind pressure and prevents the accumulation of dust or water, making them ideal for PV site perimeter barriers, surveillance poles, and equipment support columns. We offer custom processing services—including beveling, threading, and drilling—and maintain a comprehensive range of pipe diameters with rapid shipping capabilities. We can also supply complete sets of matching PV steel structural accessories for consolidated delivery. Full material inspection documentation is provided directly from the factory, ensuring compliance with construction acceptance standards for both inland and coastal PV projects, as well as requirements for export.

Guojian Factory is a professional manufacturer and supplier of Solar Panel Clamps. This product is an indispensable fastening component in the construction of photovoltaic power stations, mainly used to fix photovoltaic modules on installation rails. They are suitable for various installation systems, including roof, ground, and carport installations.

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.
