Steel Structure Characteristics
1. Beautiful and practical:
Steel structure building has diverse designs with various styles
and colors.
2. High fire resistance:
Fireproof coating is usually applied on the surface of steel
structure, which forms a protective film and improves the fire
resistance limit of the components.
3. Sound insulation and heat preservation:
Composite panels are used for roof and wall.

Product Parameters
Steel structure warehouse/workshop is steel structure built over a
structural concept of primary members, secondary members, roof and
wall sheeting connected to each other and various other building
components. These buildings can be provided with different
structural and non-structural additions such as skylights, wall
lights, turbo vents, ridge ventilators, louvers, roof monitors,
doors windows, trusses, mezzanine floors, fascias, canopies, crane
systems, insulation etc., based on the customer's requirements.
Steel structures are commonly used in the construction of various
industrial factories, workshops, warehouses, and farm buildings due
to their excellent load-bearing capacity and flexible design.
Additionally, steel structures have high strength and low weight,
making them suitable for bearing heavy loads and spanning large
spaces. This is why they are often used in the construction of
high-rise buildings, sports stadiums, large commercial buildings,
exhibition halls, and more.
