Steel stair formwork is a modularly designed professional concrete forming system specifically developed to provide high-precision, high-efficiency stair casting solutions for modern construction projects. The product is made of 6mm thick Q355B high-strength steel plates as the main structure, reinforced with #12 channel steel frames, and undergoes both hot-dip galvanizing and fluorocarbon spray treatment to ensure excellent performance in harsh construction environments.
