Long Description
We provide professional custom heavy duty steel base plate and machine mounting plate welding fabrication service, focusing on high-load, high-precision equipment fixed support scenarios. Adopting high-strength thick carbon steel and structural steel plates, we integrate cutting, welding, stress relief treatment and precision machining to manufacture stable, deformation-resistant and high-load-bearing base products.
Aimed at large industrial machines, automation equipment, precision instruments and heavy machinery mounting demands, our products feature ultra-high structural stability and flatness. We carry out mandatory stress relief heat treatment after welding to thoroughly eliminate residual stress, avoiding long-term deformation and ensuring equipment operation accuracy. All welding joints adopt full penetration welding, with firm structure and strong tensile and pressure resistance.
We support customized processing of various sizes, thicknesses and hole positions, with CNC precision machining to ensure flatness and dimensional accuracy. We can also carry out anti-corrosion surface treatment according to customer usage scenarios, prolonging product service life. With rich experience in heavy base fabrication, we strictly control each process to meet industrial equipment high-standard mounting requirements.
