Customized Prefabricated Light Steel Frame Industrial Workshop Building With Large Span

Description

Steel structure building is a construction where the vertical and horizontal loads are supported by a frame of structural steel elements. This framework, consisting mainly of I-beams, HSS (Hollow Structural Sections), and other shapes, is often prefabricated off-site, allowing for rapid erection and high precision. Steel's high strength-to-weight ratio makes these buildings ideal for large-span projects and high-rise construction, offering design flexibility and superior seismic resistance compared to traditional concrete or timber structures.

Painting system on peb steel structure surface:

There are two principal methods for providing corrosion protection to steel structures: anti-rust painting and hot-dip galvanization.

Anti-Rust Painting (Protective Coating Systems)

Anti-rust painting involves applying a multi-layer coating system to the steel surface. This method creates a physical barrier that prevents corrosive elements like moisture and oxygen from reaching the metal. A typical system involves:

1. Surface Preparation: This is crucial and often involves abrasive blast cleaning (sandblasting) to remove mill scale, rust, and contaminants, creating a clean, roughened surface for optimal paint adhesion.

2. Primer Coat: The first layer applied is usually a primer that contains corrosion-inhibiting pigments, such as zinc phosphate or zinc-rich compounds. The primer is key to the system's anti-rust performance.

3. Intermediate/Tie Coats: One or more intermediate coats are applied to build up the film thickness, providing additional barrier protection and improving the bond between the primer and the topcoat.

4. Topcoat/Finish Coat: This final coat provides the required color, UV resistance, and resistance to environmental factors and chemicals. Common paint types used include epoxies, polyurethanes, and alkyds.

Painting offers flexibility in color and finish and is suitable for on-site application and repair, though its long-term performance is heavily dependent on the quality of the surface preparation and application.

Hot-Dip Galvanization (HDG)

Hot-dip galvanization is a process that provides a much more robust and long-lasting form of corrosion protection. The process involves:

1. Preparation: The steel component is chemically cleaned using a degreasing bath, followed by an acid pickling bath to remove rust and scale. It is then fluxed to prepare the surface for bonding.

2. Dipping: The clean steel is completely submerged in a bath of molten zinc (heated to approximately 450∘C or 840∘F).

3. Metallurgical Bonding: While submerged, the iron in the steel metallurgically reacts with the molten zinc to form a series of highly durable zinc-iron alloy layers, followed by a pure zinc layer on the surface.

The key advantage of HDG is its dual protection mechanism: it acts as a tough physical barrier, and critically, if the coating is scratched, the zinc provides cathodic protection (or sacrificial protection) to the underlying steel, meaning the zinc will corrode first, sparing the steel from rust. This process provides complete coverage, even in complex shapes and recessed areas, leading to service lives that can exceed 50 years in many environments with minimal maintenance.

Common Applications of Steel Structure Building:

• Industrial Buildings: Steel is the dominant material for large-scale factories, warehouses, and manufacturing plants because it allows for wide, open spans, accommodating large machinery and flexible layouts.

• High-Rise and Skyscrapers: Steel frames are essential for constructing tall buildings because of their high strength-to-weight ratio and ability to resist high wind and seismic forces.

• Commercial Centers: They are widely used for shopping malls, office complexes, exhibition halls, and convention centers, offering design flexibility for large, column-free interior spaces.

• Infrastructure Projects: Steel is critical in bridges, railway stations, and airport terminals, valued for its durability and the speed at which complex structures can be erected.

• Agricultural and Storage: Steel structures form the basis of barns, storage sheds, and grain silos due to their cost-effectiveness, durability, and protection against the elements.

• Residential and Modular Construction: While less common than concrete for traditional homes, steel is increasingly used in modular construction and for multi-story residential buildings and apartments.

• Specialty and Recreational Structures: This includes stadiums, sports arenas, theaters, and aircraft hangars, where long-span roofs and specialized geometric designs are required.
