Heavy Duty Modular Welding Platform for Door Frame Welding

This heavy duty modular welding platform measures 2000mm in width and 3000mm in length, featuring 28mm (D28) holes arranged in a standard 100*100mm grid pattern. The table thickness is typically 25mm or 28mm (customizable), with a precision-ground and induction-hardened surface.

Door frame welding requires large, flat, and rigid surfaces to maintain squareness and prevent warping. This 2000*3000mm platform accommodates multiple door frames simultaneously-ideal for industrial production of steel fire doors, commercial entrance doors, and residential security doors. The modular clamping system allows quick changeover between different frame sizes.

The platform is manufactured from high-strength cast iron (GG30/GGG50) or optional heavy-duty Q355B steel. The surface is induction-hardened to HRC 45-50 and precision-ground, providing excellent wear resistance, vibration damping, and deformation resistance under repeated heavy use.

This heavy duty platform safely supports distributed loads up to 5000kg (5 tons) and point loads up to 2500kg. It is designed to handle multiple steel door frames, heavy clamping fixtures, and repeated welding cycles without deflection.

"Modular" means the platform features a grid of precision holes that work with a complete family of interchangeable clamping components-clamps, stops, locating pins, angle brackets, riser blocks, and square rulers. You can reconfigure the setup for different door frame sizes (e.g., 700*2100mm, 900*2100mm, 1000*2200mm) in minutes without any special tools.
