Product Description

 

Product Description

C-shaped steel is automatically processed and formed by a C-

shaped steel forming machine. The C-shaped steel forming

machine can automatically complete the forming process of C-

shaped steel based on the given C-shaped steel size. C-shaped

steel is widely used in purlins, wall beams of steel structures, and

can also be self assembled into lightweight building components

such as roof trusses and brackets. In addition, it can also be used

for columns, beams, and arms in mechanical light industry

manufacturing.

Cold formed Z-shaped steel has the advantages of adjustable

specifications and high compressive strength. It is widely used in

fields such as automobiles, railway vehicles, building doors and

windows, transportation, shelves, electrical cabinets, highway

guardrails, building steel structures, containers, steel formwork

and scaffolding, solar powered support shipbuilding, bridges,

transmission towers, steel sheet piles, cable trays, agricultural

machinery, furniture, warehousing, guide rails, keel steel,

vegetable greenhouses, pipeline supports, municipal
