Steel frames packed and shipment for small warehouse in Togo

To address the storage needs of a small-scale warehouse project in Togo, Yirong company has delivered a prefabricated steel frames solution that combines high efficiency, climate resilience, and cost-effectiveness. The project utilizes H-shaped steel beams and columns as the structural backbone, paired with precision-engineered purlins to ensure optimal load-bearing performance and rapid on-site assembly.

Structural Framework: H-Shaped Steel Beams & Columns

Material Selection

Grade: Q345B carbon structural steel (ASTM A572 equivalent), offering a tensile strength of 450MPa and excellent weldability.
Surface Treatment: Hot-dip galvanized coating (Z450g/m²) for anti-corrosion protection, ensuring durability in Togo’s humid tropical climate.

H-Shaped Steel Process

Hot-Rolled Technology: Manufactured via continuous hot-rolling to achieve precise cross-sectional geometry (HW series), minimizing residual stress.

Section Advantages:

I-beam Profile: Provides 20% higher load capacity compared to traditional I-beams, ideal for heavy racking systems.
Web-Stiffened Design: Reinforced flanges and web thickness (12mm–16mm) enhance stability against wind uplift and seismic loads.

Modular Assembly

Pre-drilled bolt holes (M16–M20) enable tool-free connections, reducing onsite labor by 40%.
Standardized H-sections (e.g., HM 250×175×6×9) ensure rapid alignment and compliance with local building codes.

Purlin System: Lightweight & High-Efficiency

Dimensions: 100mm×50mm C-shaped purlins with 5mm galvanized steel thickness, spaced at 1.5m intervals.

Performance:

Snow Load Capacity: 1.5kN/m² (exceeds Togo’s tropical storm resistance requirements).
Corrosion Resistance: Galvanized coating with polyurethane paint finish for UV protection.

Project Execution

Factory Prefabrication: Full-scale CNC cutting and welding ensure ±1mm dimensional accuracy, minimizing onsite adjustments.
Packaging & Logistics: Disassembled into modular bundles with anti-rust paper padding; shipped via 40HQ container for timely delivery.
