Product Overview
Bed Base with Castors is an industrial-grade, mobile steel foundation engineered for hospitality, healthcare, and residential contract furniture. This heavy-duty bed base integrates low-profile, reinforced casters directly into the structural frame, providing seamless room reconfiguration and effortless cleaning access without compromising structural rigidity.
Performance Data & Manufacturing Craft
Stress-Distribution Welding: Structural joints utilize automated robotic MIG welding with full-penetration seams, preventing frame sag or rattling under intense dynamic loads.
Low-Clearance Mobility: Integrated recessed brackets lower the bed base center of gravity, keeping the overall platform height under 150mm while maintaining 50mm of floor clearance for easy vacuum access.
Impact-Resistant Edge Buffering: All corner brackets undergo continuous radius pressing to remove sharp edges, protecting hotel walls and housekeeping staff from impact damage.
Zero-Degradation Glides: Optional hybrid designs utilize non-marking polyurethane twin-wheels with internal steel solid axles, ensuring flat-spot resistance even when left stationary for months.
Strict Quality Control & Load Verification
Raw Material Analysis
Digital ultrasonic testing of incoming steel tube wall thickness and non-destructive hardness testing of molded caster polymers.
Weld Seam Testing
Regular destructive tear testing and macro-etch examinations on sample robotic weld joints to verify deep penetration and zero porosity.
Dynamic Fatigue Pressing
Full-frame testing apparatus applies continuous cyclical loads exceeding 100,000 repetitions to simulate a 10-year commercial service life.
Salt Spray Passivation
Coated steel components endure 72-hour salt spray testing to guarantee complete finish adhesion and rust-free performance in tropical or humid environments.

FAQ
Q: Does the rolling frame structure transfer motion or create noise when two people occupy the bed?
A: No. The base eliminates the traditional drop-in stem connection. The caster housing is bolted directly into a structural steel plate welded to the main frame channel. This metal-to-metal fixed integration eliminates sway and prevents structural squeaking.
Q: What prevents the entire bed base from sliding on slick polished tile or vinyl flooring?
A: Our hospitality bases utilize diagonal twin-locking casters. Stepping down on the reinforced steel pedal creates a high-friction mechanical lock against the wheel tread. For slick floors, we specify high-durometer rubberized treads that grip smooth surfaces without slipping.
Q: How does a knock-down (KD) frame compare in strength to a fully welded one-piece base?
A: Our KD frames use grade-8.8 high-tensile structural bolts and internal reinforcement sleeves at all joining corners. Once tightened, the mechanical interlocking joint matches the structural shear strength of a continuous weld while saving massive shipping volume.
Q: Can the frame withstand the harsh sanitizing chemicals used in commercial healthcare laundries?
A: Yes. The frame is coated with an industrial epoxy powder layer cured at 200 degrees Celsius. This creates a dense, non-porous barrier that resists scratching and prevents degradation from commercial quaternary ammonium compounds and isopropyl alcohol sanitizers.
Q: We need a specific clearance height to allow under-bed luggage storage in our hotel design. Can you adjust this?
A: Yes. We can alter the vertical drop of the corner plates or increase the main tube clearance during the metal stamping process. We regularly adjust the under-bed clearance from 100mm to 200mm to fit standard hospitality luggage profiles.
Q: Do you supply the mattress retention lip or non-slip padding to keep the mattress from moving?
A: Yes. The base can be manufactured with either an integrated 20mm recessed steel border or with high-friction polymer pads factory-adhered to the steel support slats to prevent mattress shifting during mobility.
Q: Can we order replacement wheels separately if they get damaged by heavy handling over several years?
A: Yes. We use standard modular mounting hole patterns for the internal caster plates. Replacement wheel modules can be shipped separately and swapped out using standard hex tools without replacing the main steel foundation.
