    Questions & Answers

    Q: What materials are used for the metal frames and bracket systems?

    Our metal frames and bracket systems are manufactured using high-grade stainless steel, carbon steel, or aluminum. They undergo surface treatments such as powder coating or galvanization to ensure excellent corrosion resistance and long-lasting durability.

    Q: Are the outdoor electrical boxes weatherproof and dustproof?

    Yes, our outdoor electrical boxes are specifically designed to withstand harsh environmental conditions. They feature robust sealing gaskets and meet high IP/NEMA rating standards to effectively protect internal electrical components from dust, rain, and moisture.

    Q: What level of tolerance can you achieve for precision mechanical structures?

    We utilize advanced CNC machining and laser cutting technologies to fabricate precision mechanical structures. Depending on the design specifications and material requirements, we can achieve tight tolerances to meet strict engineering standards.

    Q: Can the slide rail and mounting systems support heavy-duty applications?

    Absolutely. Our slide rail and mounting systems are engineered for high load-bearing capacity and smooth operation. They are ideal for server racks, industrial equipment, and custom mechanical assemblies requiring reliable slide mechanisms.

    Q: Do you offer customization options for these metal components?

    Yes, we provide comprehensive OEM and ODM services. All products, including metal frames, electrical boxes, mechanical structures, and slide systems, can be customized in terms of dimensions, material thickness, finishes, and mounting configurations according to your specific drawings.
