PR message
Duong Dai specializes in custom sheet metal fabrication and raw material supply including stainless steel 304/316, carbon steel, galvanized steel, and aluminum sheets. We offer CNC laser cutting, CNC bending, TIG/MIG welding, electrical enclosures, cable trays, precision components with ISO-certified in-house production in Hanoi, fast lead time, flexible MOQ, and competitive export pricing.
We manufacture custom sheet metal electrical enclosures with high ingress protection ratings (IP55–IP65), suitable for both indoor and outdoor industrial environments. Unlike standard suppliers, we support fully customized designs including cutouts, hinges, locking systems, mounting flanges, and surface treatments per client specifications. Materials include galvanized steel, stainless steel 304/316, with options for powder coating or brushed finish. We provide flexible low- to mid-volume OEM service with tight quality control, ensuring each unit meets dimensional and mechanical standards for panel builders and automation system integrators.
Our stainless steel cable trays and support systems are available in 1–3m lengths with customizable punching patterns and thicknesses. While many suppliers offer only fixed models, we manufacture according to your drawings or samples, ensuring compatibility with international industrial standards. All accessories such as couplers, wall brackets, suspension hangers are matched for fast and reliable installation. Material options include SS304 and SS316, with surface finish ranging from mill to brushed. Our system helps reduce installation errors and project delays for industrial construction sites and MEP contractors.
We produce high-precision steel brackets, base plates, and fixing parts tailored to individual client requirements. Unlike mass manufacturers, we focus on low to medium volume custom production with tight tolerances. All parts undergo laser cutting, drilling, bending, and optional welding or surface finishing. Flatness, perpendicularity, and parallelism are checked to meet mechanical and assembly standards. Ideal for machine builders, structural frameworks, solar racking systems, and OEM hardware solutions, we ensure functional accuracy and fast delivery at competitive pricing.
Our value-added services include polishing, deburring, laser marking, and simple product assembly to deliver components ready for end use. While many suppliers only provide raw fabricated parts, we offer complete finishing solutions to reduce your downstream costs. Logos, serial numbers, or barcodes can be engraved on metal surfaces. We ensure sharp edge removal, smooth finishing, and even final packaging. For OEM customers, we can assemble multiple parts and ship as a completed unit. This simplifies your supply chain, especially for small-to-medium batch production.
Our welding process is distinguished by highly skilled welders, precise temperature control, and jig-based positioning. Many workshops still rely on manual welding with inconsistent quality, but we utilize digitally controlled TIG/MIG machines to ensure strong, clean welds with minimal post-processing. We handle stainless steel and mild steel from 1mm to 10mm thick. Weld seams are inspected and can be finished as required. Our ability to combine welding with cutting, bending, and finishing operations allows us to deliver fully assembled parts that meet demanding industrial applications and aesthetic standards.
We offer highly flexible production for both small and large batches, covering various materials such as stainless steel, mild steel, and aluminum. Unlike companies that rely solely on standard molds or fixed templates, we specialize in custom fabrication based on customer drawings. Our engineers process CAD/STEP files quickly into production, backed by ISO-certified quality control to ensure mechanical precision and reliability. We handle complex shapes, tight tolerances, and offer complete traceability from material sourcing to final inspection. This makes us a trusted OEM partner for global industrial clients.
We offer end-to-end sheet metal fabrication services in Vietnam, including CNC laser cutting, CNC bending, TIG/MIG welding, electrical enclosure manufacturing, and custom assembly based on technical drawings.
Our greatest advantage lies in a fully in-house production process, ISO-compliant quality control, rapid DFM feedback, short lead times, and flexibility in order quantities.
Customers receive optimized solutions from design to final product, reducing costs while ensuring high precision—tolerances as tight as ±0.1mm.
