Tianjin Emerson Metal Steel Products Co., Ltd. is proud to present A3 & A36 Custom Sheet Metal Welding, Bending, Laser Cutting & Waterjet Cutting Parts under the EMERSONMETAL brand. As a professional metal processing factory, we specialize in delivering tailored fabrication solutions for A3 and A36 carbon steel—two of the most versatile and widely used structural steels in industrial applications. Our services combine advanced cutting technologies (laser and waterjet cutting) with precision bending and welding, ensuring that every part meets your exact design specifications.
A3 and A36 are low-carbon structural steels celebrated for their balanced properties. A3 (equivalent to China’s Q235) offers excellent formability and weldability, making it ideal for general-purpose fabrication where cost-effectiveness and ease of processing are key. A36, a standard in North American markets, boasts slightly higher tensile strength (≥400 MPa) and better ductility, making it suitable for load-bearing applications that require both strength and flexibility. Both grades share core advantages: they are easy to machine, compatible with various welding methods, and available at a competitive price point—qualities that have made them staples in construction, machinery, and automotive industries.
What sets our service apart is our ability to handle diverse fabrication needs through advanced cutting technologies. Our laser cutting machines deliver exceptional precision, achieving tolerances as tight as ±0.1mm for thin to medium sheets (1mm–20mm thick). This ensures clean, burr-free edges and intricate shapes—critical for parts requiring precise assembly, such as machinery brackets or automotive components. For thicker materials (up to 300mm thick), we use waterjet cutting, a cold-cutting method that avoids heat-induced distortion, preserving the steel’s structural integrity. This is particularly valuable for heavy-duty parts like industrial machine frames or pressure vessel components.
Beyond cutting, we offer comprehensive post-processing services. Bending is performed using CNC-controlled machines to ensure accurate angles and consistent dimensions, even for complex geometries. Welding is executed by certified technicians using techniques (MIG, TIG, and arc welding) that maintain joint strength—essential for structural parts like steel beams or support frames. We also provide surface treatments such as painting or galvanizing to enhance corrosion resistance, extending part lifespan in outdoor or humid environments.
Customization is at the heart of our service. Whether you need a single prototype or large-volume production, we accommodate orders starting from 1 piece, with the flexibility to adjust sizes, shapes, and finishes based on your drawings. Our quality control process includes material inspections, dimensional checks, and performance testing, ensuring that every part meets industry standards for reliability and durability.

Application Scenarios
A3 and A36 steels are versatile enough to serve across multiple industries, with their specific properties catering to distinct needs:
Construction and Infrastructure: A3 is widely used in general structural components such as scaffolding, roof trusses, and mild steel frames, where its formability simplifies on-site assembly. A36, with its higher strength, is preferred for load-bearing structures like bridge girders, building columns, and heavy-duty supports—its ductility helps absorb shocks from earthquakes or dynamic loads.
Automotive and Machinery: A3 is ideal for non-critical automotive parts like brackets, panels, and chassis components, where cost and weldability are prioritized. A36 is used in heavier machinery, such as tractor frames, crane booms, and conveyor systems, where its tensile strength resists wear and deformation under stress.
Industrial Fabrication: Both grades are used to make machine guards, storage racks, and tooling plates. A3’s ease of cutting makes it suitable for DIY projects or low-volume parts, while A36’s precision ensures stability in high-performance equipment like hydraulic presses or manufacturing lines.
Outdoor and Agricultural Equipment: When galvanized or painted, A3 and A36 resist rust in outdoor settings. They are used in agricultural machinery (e.g., plow frames, irrigation system supports) and outdoor furniture, where their durability and low maintenance needs reduce long-term costs.
Frequently Asked Questions (FAQ)
What is the key difference between A3 and A36, and how do I choose? A3 (Q235) offers better formability and lower cost, making it ideal for general-purpose, non-load-bearing parts. A36 provides higher tensile strength and yield strength, suitable for structural or heavy-duty applications. Choose A3 for simple brackets, panels, or low-stress parts; opt for A36 for bridge components, machine frames, or parts needing to withstand heavy loads.
Can you cut very thick sheets (over 100mm) without compromising precision? Yes. For sheets over 20mm, we use waterjet cutting, which handles thicknesses up to 300mm while maintaining tolerances of ±0.3mm. This method uses high-pressure water mixed with abrasives to cut through steel without generating heat, avoiding warping or material weakening—critical for thick structural parts like industrial machine bases.
What welding methods do you use, and how do they affect joint strength? We use MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and arc welding, selected based on part thickness and application. MIG welding is efficient for thick sheets and bulk production, ensuring strong joints for structural parts. TIG welding is used for thin sheets or precision parts (e.g., automotive components) where clean, high-quality welds are needed. All welded joints undergo strength testing to meet industry standards.
How do surface treatments enhance corrosion resistance for outdoor use? We offer galvanizing (zinc coating) and epoxy painting for outdoor applications. Galvanizing forms a protective zinc layer that resists rust, extending part life by 5–10 years in humid or coastal environments. Epoxy painting adds a barrier against moisture and chemicals, ideal for agricultural or industrial equipment exposed to fertilizers or mild corrosives. For highly humid areas, we recommend galvanizing with a top coat of paint for dual protection.
What is the lead time for custom orders, and can you handle urgent requests? Lead time depends on part complexity and quantity. For simple laser-cut parts (1–50 pieces, 1mm–20mm thick), delivery takes 3–5 working days. For thick waterjet-cut parts (over 50mm) or large orders (100+ pieces), lead times extend to 7–10 working days. Urgent orders can be expedited: small batches (1–10 pieces) with simple designs can be completed in 2–3 working days for an additional fee. We confirm timelines after reviewing your drawings.
