The Steel Platform Bed Frame uses cold-rolled carbon steel profiles with a modular knocked-down frame architecture, designed to sustain maximum mechanical stability and package volume efficiency. Precision laser cutting and automated MIG welding produce precise joint alignment, preventing frame distortion and squeak noise under heavy continuous loads. A thermosetting powder coating layer provides corrosion resistance across various climate environments.
Key Features
Cold-Rolled Steel Construction
Engineered with high-tensile carbon steel tubing to resist frame sagging and deformation.
Modular Knock-Down Architecture
Precision-fitted steel components reduce carton dimensions and optimize container loading space.
Integrated Center Support
Longitudinal center beam and vertical steel posts evenly distribute surface pressure.
Continuous Mattress Base
Interlocked transverse steel slats deliver direct mattress support without box springs.
Multi-Stage Powder Coating
Chemically pre-treated surface finishing prevents rust formation and scratch damage.
Flexible Custom Production
Adaptable frame dimensions, steel gauges, coating colors, and packaging setups.
Structural Design
Main Frame: Rectangular outer perimeter welded at fixed right angles for structural squareness.
Center Support: Longitudinal steel beam supported by heavy-duty mid-frame vertical posts.
Crossbars: Transverse steel slat matrix fitted directly into side rails to prevent frame shifting.
Support Legs: Tubular vertical legs capped with floor-protection pads to prevent floor abrasion.
Connections: Steel-to-steel direct bolt assembly using self-locking hardware to ensure structural firmness.
Modular Sections: Interconnected sub-assemblies designed for tool-assisted rapid site assembly.

Frequently Asked Questions
Q: What bed sizes are available for order?
A: Standard sizes include Twin, Full, Queen, and King. Dimensional alterations can be manufactured according to regional specifications.
Q: What steel grades and wall thicknesses are used?
A: Cold-rolled carbon steel grades Q195 and Q235 are standard. Tube wall thickness ranges from 0.8 mm to 2.0 mm depending on structural requirements.
Q: What is the static load capacity of the frame?
A: Queen and King frame configurations support up to 1,500 kg of evenly distributed static weight without structural yield.
Q: Are custom frame dimensions supported?
A: Yes. Adjustments can be made to length, width, clearance height, slat density, leg count, and bracket positions.
Q: How is the steel protected against surface rust?
A: Steel tubing undergoes a 7-stage chemical pre-treatment and zinc phosphating process before receiving an electrostatic powder coating cured at high temperature.
Q: What is the minimum order requirement and production lead time?
A: Minimum order quantities start at 200 units per size and finish. Production lead times range from 30 to 45 days following final specification sign-off.
