Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
We are a professional manufacturer focusing on custom 1U/2U rack-mount server chassis and industrial control sheet metal enclosures. We specialize in high-precision industrial sheet metal customization, serving global customers in network communication, industrial automation, server hardware and intelligent control fields.

Common Industry Pain Points
Most traditional sheet metal manufacturers have huge limitations in order flexibility and quality control. They typically refuse prototype customization and only support large-batch orders. Common industry issues include inaccurate rack mounting sizes, rough welding seams, uneven surface coating and structural deformation. Unstable product quality and uncontrollable delivery cycles often hinder customers’ R&D testing, project iteration and market launch progress.

Our Unique Strengths & Solutions
We perfectly solve all the above industry pain points for global purchasers. Breaking the traditional manufacturing limitations, we support 1 piece minimum order, covering custom prototyping, small-batch trial production and large-scale mass production. Our highly flexible production mode fully meets your needs in every project stage, from early R&D verification and technical iteration to formal bulk delivery.
All our 1U/2U rack chassis are manufactured with strict standard tolerance control, ensuring precise rack installation, flawless assembly and excellent equipment compatibility. We adopt premium cold-rolled steel, galvanized steel and 304 stainless steel as raw materials, matched with fine welding, precision grinding and uniform industrial powder coating processes. The finished chassis features outstanding rust resistance, corrosion resistance and scratch resistance, with stable overall structure, perfectly adapting to long-term operation in indoor and complex industrial environments.
We provide full-process one-stop OEM & ODM customization services, including personalized size adjustment, precision hole opening, structural optimization, bending modification, logo engraving and custom surface finishing. Equipped with independent production workshops and complete precision processing equipment, we implement strict full-range quality inspection to completely avoid defective products and quality instability. Flexible production scheduling ensures stable quality and punctual delivery for every order.
