We primarily use high-quality, commercial-grade carbon steel for our bunk bed frames. The steel tubes are cold-rolled for enhanced strength and precision. For specific applications requiring higher corrosion resistance, such as maritime or coastal environments, we can manufacture beds using galvanized steel or apply specialized anti-rust coatings as part of our OEM/ODM services. All materials conform to international standards for safety and durability, ensuring a robust and long-lasting product. The thickness of the steel can also be customized based on your project's load-bearing requirements.

Our standard heavy duty metal bunk beds for adults are rigorously tested and rated to hold a static load of 150kg to 200kg (approximately 330 to 440 lbs) per bunk. For projects with more demanding requirements, such as military or industrial use, we can engineer and manufacture beds with a higher weight capacity. This involves using thicker gauge steel, additional support beams, and reinforced welding points. Please specify your required weight capacity during the quotation process for a custom solution.

We use an environmentally friendly electrostatic powder-coating process. This method provides a much more durable, uniform, and long-lasting finish compared to conventional liquid paint. The powder coating is resistant to scratches, chipping, fading, and rust, making it ideal for high-traffic institutional environments. We offer a wide range of standard colors (black, white, silver/grey) and can accommodate custom color requests based on the RAL color system for large-volume orders.

As a factory specializing in bed frames, our standard pricing does not include mattresses. This allows our clients to source mattresses locally based on their specific comfort, hygiene, and budget requirements. However, for large-scale turnkey projects, we can leverage our supply chain to source and consolidate mattresses into your shipment. We can provide standard mattress dimensions (e.g., Twin, Full) to ensure a perfect fit for our frames.

Many of our most popular models are designed to be detachable. This feature offers excellent versatility, allowing you to configure them as a single bunk bed or as two separate, stand-alone twin or full beds. This is particularly useful for multi-purpose rooms or facilities where needs may change over time. Please check the product description for the "detachable" feature or specify this requirement when you request a quote for your project.

As a factory-direct exporter specializing in B2B and large projects, our Minimum Order Quantity (MOQ) is typically set to fill a 20-foot shipping container (20' GP), which can hold a significant number of bunk beds depending on the model. This approach ensures the most cost-effective shipping and handling for our clients. For specific MOQ details on a particular model or for a mixed-model order, please contact our sales team.

We are flexible and can work with various Incoterms to suit your logistical needs. The most common terms we use are FOB (Free On Board), where we handle delivery to the port of loading in our country; CFR (Cost and Freight), where we arrange and pay for shipping to your destination port; and CIF (Cost, Insurance, and Freight), which also includes marine insurance. We can also provide EXW (Ex Works) pricing if you wish to handle all logistics from our factory gate.

We use robust, export-standard packaging to ensure your order arrives in perfect condition. The beds are shipped in a knock-down (KD) format to maximize container space and reduce shipping costs. Each component is individually wrapped in protective material (like EPE foam or bubble wrap) and then tightly packed into durable, multi-layer corrugated cardboard cartons. Cartons are clearly labeled with model numbers, quantities, and handling instructions to facilitate easy unloading and inventory management at your end.

Production lead time depends on the order size, model complexity, and our current production schedule. For a standard order of one 40' HQ container, the typical lead time is between 25 to 40 days after order confirmation and receipt of deposit. For custom OEM/ODM orders, an additional 7-15 days may be required for mold creation and sample approval. We will provide a more precise delivery schedule with your formal quotation.

Our standard payment terms for international orders are a 30% deposit via Telegraphic Transfer (T/T) to confirm the order and begin production. The remaining 70% balance is due upon completion of the order, against the presentation of the Bill of Lading (B/L) copy and other shipping documents. For long-term partners with established relationships, we may be open to discussing other payment arrangements, such as a Letter of Credit (L/C) for very large orders.

Yes, absolutely. We have a dedicated R&D and engineering team to handle OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) projects. You can provide us with detailed drawings, specifications, or even just a concept. Our team will work with you to create technical drawings, produce a prototype for approval, and then move to mass production. We are your factory partner in bringing your unique design to life.

We offer extensive customization. Key customizable aspects include:
1. Dimensions: Overall height, length, width, and clearance between bunks.
2. Materials: Steel tube thickness and profile (round/square).
3. Color: Any color from the RAL chart for the powder-coating.
4. Features: Ladder design (straight/angled), guardrail height and style, addition of storage brackets, lockers, or desk attachments.
5. Branding: We can emboss or add a metal plate with your company logo for large orders.

Yes, there is a cost associated with producing a custom prototype, which covers engineering time, materials, and mold adjustments. The exact cost depends on the complexity of the design. However, this sample fee is often partially or fully refundable upon placement of a bulk production order that meets a certain volume threshold. This ensures we are partnering with serious clients for custom development.

Our bunk beds are designed and manufactured with safety as the foremost priority. They are built in accordance with major international safety standards, such as EN 747-1/2 (European standard for domestic bunk beds) and ASTM F1427 (American standard). These standards govern structural integrity, guardrail height, ladder construction, and entrapment hazard prevention. Our factory is also ISO 9001 certified for quality management, ensuring consistent production standards.

Yes. We welcome and can facilitate third-party inspections from reputable agencies like SGS, Intertek, or Bureau Veritas. Clients can arrange for an inspector to visit our factory for a pre-shipment inspection (PSI) to verify quality, quantities, and packaging against the order specifications. We can also provide our own internal QC reports and material certificates upon request, demonstrating our commitment to transparency and quality assurance.
