About Our Custom Sheet Metal Fabrication Service
Our custom sheet metal fabrication service is designed to meet a wide range of manufacturing needs. Below are some of the most common questions we receive, along with our responses, which reflect our dedication to quality, precision, and customer satisfaction.
What range of sizes and thicknesses can you handle in your sheet metal fabrication process?
We can accommodate metal thicknesses up to 25mm and have the capabilities to work with a vast array of sizes, including exceptionally long or wide products. Our flexibility allows us to produce according to your specifications and, if necessary, collaborate with our network of suppliers to outsource certain steps to handle even the most demanding industrial sheet metal manufacturing projects.
What level of precision does your custom sheet metal fabrication offer?
Our cutting and punching processes typically achieve a dimensional and shape tolerance of ±0.1 mm, while for bending, we maintain an angle tolerance within ±0.3°. This high level of precision ensures that components fit and function as intended in their final applications.
Which surface treatments are available through your service?
Our surface treatment options are extensive, including but not limited to painting, electroplating, anodizing, sandblasting, and polishing. These finishing processes enhance the appearance and durability of the final product, catering to various aesthetic and functional requirements.
Can you manufacture products according to ISO standards and specific drawing tolerances?
Absolutely. We meticulously review all drawing requirements before production and interpret the standard and specific grade requirements included. We consistently monitor our production process to ensure compliance with these standards.
What is the minimum order quantity, and what are your lead times?
We accept sample orders and pride ourselves on accommodating low-volume production runs. Lead times vary depending on the complexity of the drawings but most projects are delivered within a 1-3 month timeframe. These are estimated times and can be refined upon project assessment.
How do you handle post-delivery issues, if any arise?
We provide comprehensive reports, including dimensions, roughness, parallelism, and flatness, along with product photos for customer verification before shipping. If any quality issues are identified upon delivery, we engage proactively to resolve them through return and repair or local maintenance solutions, depending on the situation and customer preference.

Materials we work with for sheet metal parts
From our strategic location on the East China coast, we leverage our robust metal raw material supply network to readily access a wide range of steel materials in stock.

Aluminum Alloys
Known for their plasticity, machinability, welding performance, and lightweight properties, aluminum alloys like 6061, 6063, 5052, 2024, and 7075 are widely used in various industries, including aerospace, automotive, maritime, and electronic machining.

Stainless Steel
With a protective chromium layer that prevents rust and corrosion, stainless steel offers high strength, rigidity, an attractive finish, and good welding properties. Common grades include Austenitic 304 and 316L, Ferritic 430, Martensitic 1Cr13 and 3Cr13, and Duplex SUS32304 and SUS31803.

Carbon Steel
Known for its strength and hardness, carbon steel can be further enhanced through heat treatment. Low carbon steel is easy to weld and form, making it suitable for low-cost mechanical processing and welding. Common grades include hot-rolled SHCC like Q235 and Q355, cold-rolled SPCC like Q195, and medium carbon steel such as 45# steel.
Sheet Metal Fabrication Part Surface Finish
- Painting: Through spray painting and heat curing, it protects sheet metal components while enhancing their appearance.
- Plating: This process deposits a layer of metal or alloy on the surface of sheet metal, such as zinc plating, nickel plating, or chrome plating, primarily to prevent corrosion and improve durability.
- Anodizing: Anodizing forms an oxide layer on the surface of sheet metal, enhancing corrosion resistance and wear resistance.
- Powder coating: Powder coating involves spraying a powder coating and then curing it with heat, providing both corrosion resistance and an aesthetic finish.
- Oxidation: This includes blackening treatment, where a chemical reaction forms a black oxide film on the surface of sheet metal, increasing corrosion resistance and aesthetic appeal.
