Built with heavy-gauge cold-rolled carbon steel, the Full Size Steel Bed Frame integrates a modular load-bearing structure engineered for long-term rigid support, simplified flat-pack assembly, and space-optimized container shipping.
Key Features
High-Strength Steel Construction
Thick-wall cold-rolled steel tubing resists structural deformation and fatigue under continuous load.
Heavy-Duty Structural Design
Uniform weight distribution geometry eliminates localized stress concentrations and frame sagging.
Modular Configuration
Knock-down component system enables compact packaging dimensions and rapid onsite assembly.
Stable Load-Bearing Performance
Longitudinal center support beams and internal crossbars eliminate lateral sway and joint friction noise.
Corrosion-Resistant Coating
Multi-stage chemical pretreatment and electrostatic powder coating deliver long-term scratch and rust protection.
OEM Customization
Dimensions, tube wall thicknesses, steel profiles, surface finishes, and packaging specs adapt to custom requirements.
Structural Design
Main Frame: Cold-rolled steel side and end rails precision-punched for square corner alignment.
Center Support: Longitudinal center steel beam supported by vertical posts to prevent span deflection.
Crossbars: Spaced steel slat bars locked into side rails to support the mattress directly.
Legs: Tubular steel support posts equipped with floor-protecting glides.
Connections: Steel bracket locking mechanisms and bolt connections maintain joint tension.
Modular Components: Pre-assembled sub-sections designed for drop-in assembly and flat packaging.
