Detailed Service Description
We provide customized welding and fabrication services for various connecting parts and fittings dedicated to steel structure buildings, covering large connecting plates, corner supports, stiffeners, embedded parts, flange plates and other auxiliary heavy steel components. These parts are the key to ensuring the overall stability and firm connection of the steel structure, and we strictly follow the building structural design drawings for processing and manufacturing.
Adopting the same high-strength structural steel as the main steel structure (Q235B/Q355B), we carry out precision cutting, drilling, milling and positioning welding to ensure that the connecting fittings are perfectly matched with the main steel beams and columns, with consistent hole position, size and interface, realizing seamless connection and firm stress. All welding seams are subjected to full inspection to avoid welding defects and ensure the overall stress stability of the steel structure.
We support non-standard customized production according to architectural design drawings, and can carry out targeted structural optimization and processing for special connection parts. Equipped with precision CNC cutting and drilling equipment, we ensure the consistency of batch parts, and can carry out supporting anti-corrosion and surface treatment, delivering finished fittings that can be directly installed and used.
