Customized Large Span Prefabricated Steel Structure Industrial
Factory Building
Description
Structural steel buildings use an engineered frame (I-beams, HSS)
for highly optimized load bearing. The use of precision factory
prefabrication is crucial, allowing for rapid assembly on the
construction site. Leveraging steel's superior strength-to-weight
ratio, these structures are perfect for tall and expansive
projects, delivering exceptional seismic performance and
unparalleled architectural freedom.

Painting system on peb steel structure surface:
The primary strategies for protecting structural steel are Anti-Rust Painting and Hot-Dip Galvanization (HDG).
Anti-Rust Painting works by establishing a multi-layered physical barrier that seals
the steel from the elements. Success requires meticulous surface preparation, such as blast
cleaning, to ensure adhesion of the corrosion-inhibiting primer,
build coats, and the final decorative/UV-resistant layer. While it offers excellent color flexibility and simple field touch-ups, its effective lifespan is entirely dependent on the application
quality.
Hot-Dip Galvanization (HDG) is a substantially more permanent solution. Components are chemically cleaned, then submerged in molten zinc to
form a resilient zinc-iron alloy bond. This galvanization offers a powerful dual defense: it acts as a superior physical barrier and provides sacrificial (cathodic) protection that actively shields the underlying steel even if the coating is
damaged. The result is guaranteed uniform coverage and a service life often
extending for decades without maintenance.
Common Applications of Steel Structure Building:
Industrial & Warehousing: Steel is the preferred material because it delivers the wide, column-free spaces necessary for factories and distribution centers to accommodate
large equipment and flexible production layouts.
Commercial & High-Rise: Essential for tall buildings, offices, and retail complexes.
Steel's superior strength efficiently manages wind and seismic forces, allowing for the creation of open, customizable interiors.
Civil Works & Transit: Highly valued for use in bridges, transit hubs, and airports due
to its longevity and the speed with which complex, large-scale structures can be
erected.
Specialty Design: It's the defining structural element for architecture-driven
projects like stadiums, arenas, and aircraft hangars that require unique geometries and massive clear spans.
Housing & Utility: Steel provides a robust and cost-effective foundation for agricultural buildings, and its use is rapidly expanding in
modern modular and multi-story residential construction.
