This heavy-duty bunk bed steel frame is manufactured with thickened high-carbon steel tubes and full seamless welding technology, forming an integrated robust bed body structure. The frame is equipped with multiple reinforced cross beams and side support columns, greatly improving overall load-bearing capacity and structural stability. It will not shake, bend or loose joints when adults and kids climb, sit and lie for long-term daily use, effectively eliminating potential safety risks. All metal surfaces undergo high-standard electrostatic anti-rust spraying treatment, which is scratch-resistant, moisture-proof and anti-corrosion, suitable for long-term placement in school dormitories, staff apartments, children bedrooms and budget hotel engineering projects. Standard pre-drilled mounting holes are reserved on all sides of the frame, enabling fast assembly with guardrails, stair ladders and bed slats without extra cutting and drilling. Reasonable hollow gap design maintains smooth air circulation inside the upper and lower bed layers, preventing damp accumulation, mildew growth and unpleasant odor. Custom sizes of length, width and height are available to meet different space demands, and the product supports large-volume bulk wholesale and OEM supporting cooperation for furniture manufacturers and engineering purchasers.
