Galvanized Bridge Column /Guardrail Plate Steel Post
M steel belt is a new type of mine support material, M steel belt adopts 3~5mm thickness of 180~320mm width coil steel plate, after cold bending W/M type, in the middle of M steel belt processing bolt hole with bolt spacing equal to bolt.
Advantages: 1. The bending modulus of M section steel is increased 37 times.
2. Steel degree increased by about 70 times.
3. The hardening effect of M section steel during cold rolling can increase the tensile strength by 12%~15%.
