Anti Corrosion Corrugated Stainless Steel Sheet Galvanized Steel Floor Decking Sheet

1. Product Overview

This product is a professional floor decking sheet for steel structures, combining corrugated stainless steel with galvanized surface treatment. The corrugated structure enhances the mechanical strength and load-bearing capacity, making it suitable for floor bearing in steel structure buildings; the galvanized coating further improves corrosion resistance, while the stainless steel base ensures long-term durability. It serves as a key component in steel structure floors, realizing the integration of bearing, protection and practicality, and greatly improving the construction efficiency and service life of steel structure projects.

2. Material & Surface Treatment

Base Material: High-quality stainless steel (optional 304/316 grade), with excellent corrosion resistance, rust resistance, ductility and mechanical strength, able to withstand the load of floor slabs and harsh construction environments. Surface Treatment: Hot-dip galvanizing or electro-galvanizing, with uniform galvanized layer (zinc layer thickness: 80-120μm), strong adhesion, good anti-rust and anti-corrosion performance. The combination of stainless steel and galvanized coating forms a dual protective layer, effectively resisting moisture, chemical erosion and atmospheric corrosion, extending the service life of the floor decking.

3. Production Standard

The product strictly complies with international industrial standards, including ASTM A240 (stainless steel standard), ASTM A653 (galvanized steel standard), EN 10088-2 and GB/T 3280-2015. All indicators such as material composition, galvanized layer thickness, corrugation size, load-bearing capacity and dimensional accuracy fully meet the standard requirements. Each batch of products undergoes strict quality inspection (including galvanized layer adhesion test, corrosion resistance test) before leaving the factory, with complete inspection reports available.

4. Product Specifications

4.1 Thickness

Conventional thickness: 0.8mm - 3.0mm (suitable for general steel structure floor decking); customized thickness: 3.0mm - 8.0mm (for heavy-duty steel structure floors). Thickness tolerance: ±0.02mm, ensuring uniform thickness, stable load-bearing capacity and no deformation under floor load.

4.2 Width & Length

Standard width: 1000mm, 1220mm, 1500mm; maximum customizable width: 2000mm. Standard length: 2440mm, 3000mm, 6000mm; support free cutting and customized length (up to 12000mm) to fit the span of steel structure floors. Length tolerance: ±0.5mm, facilitating on-site splicing and installation.

4.3 Corrugation Specifications

Corrugation type: Trapezoidal corrugation (optimized for floor decking, good load-bearing and drainage), arc corrugation (optional); corrugation height: 20mm - 50mm; corrugation pitch: 75mm - 150mm. The corrugated structure is precision-formed, with uniform shape, strong pressure resistance and good bonding performance with concrete, ensuring the stability of the floor structure.

5. Processing Performance

• Cutting: Suitable for laser cutting, shearing and plasma cutting, with high cutting accuracy, flat surface and no burrs, which can be cut into any size according to steel structure design drawings.
• Bending: It can be flexibly bent according to the edge and corner requirements of steel structure floors, with accurate bending angle and no wrinkles, ensuring tight fitting with steel beams and columns.
• Welding: The stainless steel base material has good weldability, and the welded seam is smooth and firm, not easy to crack, ensuring the connection stability between the floor decking and the steel structure.

6. Application Fields (Steel Structure)

• Industrial Steel Structures: Steel structure workshops, factories, warehouses, logistics centers, where high load-bearing and corrosion resistance are required for floors.
• Civil Steel Structures: High-rise residential buildings, office buildings, commercial complexes with steel structure floors, prefabricated buildings, modular buildings.
• Public Facilities: Stadiums, exhibition halls, airports, railway stations, etc., with large-span steel structure floors.
• Other Scenarios: Temporary steel structure buildings, construction site temporary floors, coastal steel structure projects (316 grade recommended), leveraging its dual corrosion resistance of stainless steel and galvanizing.

7. Product Advantages

• Strong Load-Bearing Capacity: Corrugated structure enhances mechanical strength, able to bear the load of floor slabs, equipment and personnel, stable and not easy to deform.
• Dual Corrosion Protection: Stainless steel base + galvanized coating, effectively resisting rust, corrosion and harsh environments, long service life (up to 35-50 years).
• Steel Structure Compatibility: Perfectly matches steel structure installation, easy to splice and weld with steel beams and columns, improving construction efficiency.
• Cost-Effective: Durable performance reduces maintenance and replacement costs; light weight reduces the overall load of the steel structure, saving construction costs.
• Eco-Friendly: Non-toxic, environmentally friendly, recyclable, complying with modern building environmental protection requirements.

8. Attention Matters

• Storage: Store in a dry, ventilated and clean warehouse, avoid contact with corrosive substances (acid, alkali, salt), prevent moisture and rust; place flat, avoid stacking heavy objects to prevent corrugation deformation.
• Transportation: Use anti-collision and anti-scratch packaging (pearl cotton, wooden boxes) to protect the galvanized surface from scratches; handle with care, no violent loading and unloading.
• Installation: Before installation, clean the surface to remove dust and oil stains; use non-corrosive fasteners; ensure tight splicing and firm welding with the steel structure; avoid scratching the galvanized layer during installation.
• Maintenance: Regularly clean the surface with neutral detergent and soft cloth, avoid using hard objects or corrosive cleaners; repair the damaged galvanized layer in time to maintain corrosion resistance.
