Built for heavy-duty structural applications, the Metal Bed Frame System incorporates a Q235B steel skeleton, high-density modular joint connections, and a multi-stage powder-coated finish to maintain dimensional stability and load integrity across high-use commercial and residential environments.
Key Features
High-Strength Steel Construction
Cold-rolled steel profiles engineered to eliminate frame flexing and maintain joint alignment under continuous force.
Heavy-Duty Structural Design
Integrated load-distribution channels mitigate central frame sagging and bolster perimeter shear strength.
Modular Configuration
Interlocking slot-and-pin components accelerate site assembly while simplifying component replacement over extended product lifecycles.
Stable Load-Bearing Performance
Direct-ground steel support posts transfer vertical and dynamic weight vectors without localized joint distortion.
Corrosion-Resistant Coating
Thermally cured electrostatic powder application forms an impenetrable shield against atmospheric oxidation and moisture.
OEM/ODM Customization
Configurable steel gauge thicknesses, structural dimensions, powder color formulations, and packaging specifications.
Structural Design
Main Frame
Cold-rolled steel side and end rails equipped with press-formed corner locking brackets.
Center Support
Longitudinal load-bearing beam coupled with vertical middle legs to eliminate mid-span deflection.
Crossbars
Recessed steel cross bars delivering structural anti-twisting resistance and direct mattress support.
Support Legs
Tubular steel posts with non-marring floor protective caps and height-leveling glides.
Connections
High-tensile hardware secured with vibration-resistant nylon lock nuts.
Modular Components
Universal slide-in bracket assemblies enabling tool-free structural setup.
