Standard Sizes of Steel Lip Channel Galvanized Roof C Section Purlins for Sale
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
construction, etc.
