Metal fabrication involves construction of structures and products using raw metal by cutting, shaping, welding, machining, and assembly. The metal fabrication is crucial, whether it is in developing tiny precision parts or building huge machinery, in the construction industry, manufacturing, energy, and transportation. The process of selecting a good metal fabrication service provider is very important in determining the quality of durability and performance of the final product. Being an OEM, or an engineering company, the right partner can spell the difference between a successful project, and a project that will cost a company a lot more by causing delays and failures.
What metal fabrication involves before choosing a provider, it is good to know what it is all about. It also encompasses a number of important processes that are laser cutting, plasma cutting, welding, forming, CNC machining, and assembling. These operations are employed in transforming raw metals such as steel, aluminum or stainless steel to finished products or components that are exact in design and structure percept.
Counterfeit products may include minor components such as brackets and plates to very large weldments and sub-assemblies in industries such as oil and gas, energy, shipping and infrastructure. Full-service fabricator can sometimes perform component production as well as the surface finishing, painting, testing and delivery.
The technical capabilities are some of the initial factors that should be evaluated when selecting a metal fabrication company. All fabricators are not in position to deal with all types of jobs.

Metal fabrication is a cornerstone of modern manufacturing, transforming raw metal materials into functional structures, components, and products that power industries and everyday life. Tall buildings to even small automotive components are produced using the process of metal fabrication which involves cutting, bending, assembling and joining metal. It is an all-purpose craft that is a mix of precision, skill and hi-tech which is used to produce anything ranging between heavy and industrial machinery, and also to the sensitive consumer products such as cutlery. This article covers information about the complexity of metal fabrication, its operations, uses, and relevance in the modern world.
Essentially, metal fabrication is a production process that entails the bending and assembly of metal into completed products or constructions. Raw materials, which may be sheet metal, plates, bars or welding wire, are manipulated using a variety of techniques in order to create the required form. Fabrication is also different from casting where molten metal is poured into molds and instead it mostly uses solid metal that is cut, bent or joined together to produce the final product.
The process of the raw material to the finished product begins with elaborate designs or shop drawings that in most cases are developed using the computer-aided design (CAD) software. Such designs are used as blueprints, which lead metalworkers in the making. These designs are then translated into real-life by skilled professionals i.e. welders, machinists, and ironworkers, with the combination of manual skill and state-of-the-art equipment. What has been produced is the large diversity of products, large-scale structural beam, and precision-engineered items used in the aerospace industry.

Metal corrosion is a silent war—constantly eroding bridges, tunnels, vehicles, machinery, and all kinds of metal structures.
Rust-covered bridges pose serious safety hazards.
With over 20 years of expertise in metal fabrication and anti-corrosion technologies, Openex understands that corrosion protection means safeguarding safety, extending lifespan, and creating value. This article will guide you through corrosion protection technologies and Openex’s solutions for carbon steel, stainless steel, and aluminum alloys.
Cathodic protection works like injecting an “electronic vaccine” into metal—artificially maintaining the metal surface in an electron-rich state to prevent corrosion. It mainly includes two methods: sacrificial anode and impressed current cathodic protection (ICCP).
By attaching a more active metal (zinc, magnesium, or aluminum) to steel structures, the active metal corrodes first and protects the main structure.
A direct current power source applies cathodic current to reduce the metal potential into a non-corrosive range. This method is suitable for large structures like pipelines, docks, and offshore platforms.
Even iconic structures like the London Eye and the Statue of Liberty use cathodic protection—one of the secrets behind their longevity.
Anodic protection is suitable for metals that easily passivate, such as stainless steel, titanium, and aluminum. By applying an anodic current, a dense oxide film forms on the metal surface—like wearing “anti-corrosion armor.”
Openex Tip: Anodic protection requires highly precise control systems—incorrect voltage can accelerate corrosion. With our advanced potential control technology, we help reduce corrosion rates to less than one-thousandth of the original.
1. Carbon steel — Cathodic protection + surface coatings
Carbon steel is highly susceptible to corrosion in seawater and soil. We recommend:
2. Stainless steel — Passivation + anodic protection
Although stainless steel is generally corrosion-resistant, it can suffer pitting in chloride-rich environments. For marine or high-salinity conditions, we recommend 316 stainless steel (its molybdenum content better resists chloride attack and lowers corrosion risk). We offer:
3. Aluminum alloys — Anodizing + coating protection
Aluminum alloys are lightweight and strong, but can be vulnerable to electrochemical corrosion. Our expertise includes:
| Metal Type | Recommended Technology | Applications |
|---|---|---|
| Carbon Steel | Cathodic protection + galvanizing/painting | Bridges, pipelines, vehicle chassis, solar frames |
| Stainless Steel | Anodic protection + passivation | Chemical tanks, food equipment, marine use |
| Aluminum Alloy | Anodizing + fluorocarbon coating | Building facades, ships, aerospace |
Openex can customize the optimal anti-corrosion solution based on your application, budget, and service life requirements.
Corrosion is the “invisible killer” of metals—but with the right knowledge and experience, it is manageable. Openex is your trusted partner not only in metal fabrication but also in corrosion prevention. Whether it's carbon steel, stainless steel, or aluminum alloy, we offer efficient, economical, and long-lasting solutions tailored to your needs.

One afternoon in March 2025, we received a message through our website:
"I have several custom metal parts that need production. Could you provide a quotation?"
This simple inquiry marked the beginning of a productive partnership that would demonstrate our comprehensive approach to metal fabrication.
The client shared 3D drawings for three metal components. While they didn't appear complicated at first glance, critical fabrication information was missing:
Without this essential information, we couldn't provide a meaningful quotation. Through careful consultation with the buyer, we uncovered the following requirements:
Initially, the customer wanted all components made from SUS304 stainless steel, which would have been expensive. After analyzing the application, we identified an opportunity for cost savings.
Considering that the fixed components wouldn't experience abrasion, we suggested carbon steel as an alternative to stainless steel. This material change offered approximately 70% cost savings while maintaining performance for the specific application.
Regarding the carbon steel grade, the customer was familiar with ASTM A36. We introduced Q235B, the Chinese equivalent, which offers identical mechanical properties at a significantly lower cost.
To address the customer's concerns about material standards, we provided detailed technical specifications for comparison:
| Chemical Compositions (% by weight, GB/T 700 standard) | |
|---|---|
| Element | Q235A / Q235B Typical Range |
| C (Carbon) | ≤ 0.22 |
| Si (Silicon) | ≤ 0.35 |
| Mn (Manganese) | 0.30 – 0.70 |
| P (Phosphorus) | ≤ 0.045 |
| S (Sulfur) | ≤ 0.045 |
| Mechanical Properties | |
|---|---|
| Property | Typical Value |
| Yield Strength | ≥ 235 MPa |
| Tensile Strength | 370 – 500 MPa |
| Elongation (δ5) | ≥ 26% (Q235A), ≥ 25% (Q235B) |
| Hardness | Approx. 120–160 HB |
Q235: Low carbon steel, cost-effective, easy to weld, suitable for general structural purposes in non-corrosive environments.
We also provided specifications for stainless steel 304 for comparison:
| Chemical Composition (% by weight, ASTM A240 standard) | |
|---|---|
| Element | Typical Range |
| C (Carbon) | ≤ 0.08 |
| Si (Silicon) | ≤ 1.00 |
| Mn (Manganese) | ≤ 2.00 |
| P (Phosphorus) | ≤ 0.045 |
| S (Sulfur) | ≤ 0.030 |
| Cr (Chromium) | 18.0 – 20.0 |
| Ni (Nickel) | 8.0 – 10.5 |
| N (Nitrogen) | ≤ 0.10 |
| Mechanical Properties | |
|---|---|
| Property | Typical Value |
| Yield Strength | ≥ 205 MPa |
| Tensile Strength | 515 – 730 MPa |
| Elongation (δ5) | ≥ 40% |
| Hardness | ≤ 187 HB (Brinell), ≤ 90 HRB, ≤ 200 HV |
SS304: Austenitic stainless steel, higher strength, excellent corrosion resistance, commonly used in food processing, chemical equipment, and indoor/outdoor applications.
After reviewing the technical data, we agreed on the following material selection:
The customer initially preferred hot-dip galvanizing (HDG) for its proven corrosion resistance. However, for small components, HDG can result in uneven, rough surfaces that lack aesthetic appeal.
While zinc plating was considered, it didn't offer sufficient corrosion protection for the required 20-year lifespan. Centrifugal HDG was another option, but it would darken the surface while still not providing the smooth finish desired.
The breakthrough came when we noticed a silver-white bolt with Dacromet coating. Widely used in the automotive industry, Dacromet offers:
Although Dacromet typically costs more than other finishing methods, our proximity to a Dacromet coating supplier minimized the price difference. We produced a sample with Dacromet coating, which the customer approved enthusiastically.
Our fabrication process began with cutting operations. We recommended laser cutting, which has become increasingly cost-effective in recent months. Our 3D laser cutting technology eliminated the need for additional processes like beveling, milling, and drilling for most components.
We established appropriate machining tolerances based on the components' applications:
| Dimensional Accuracy: | ±0.05 mm ～ ±0.1 mm |
| Cut Edge Perpendicularity: | Almost perpendicular, within 0.1 mm |
| Surface Roughness (Ra): | Ra 6.3 to 12.5 μm |
| Angle Accuracy: | ±0.5° – ±1° |
| Dimensional Tolerance: | ±0.5 mm |
| Repeatability: | ±0.1 – 0.2 mm |
| Dimensional Accuracy: | IT7-IT8 (For round bars with diameter of 10 to 18 mm, tolerance range is ±0.009 to ±0.013 mm) |
| Surface Roughness (Ra): | Ra 1.6 – 3.2 μm |
Our detailed quotation and technical approach impressed the customer so much that they immediately placed the order, even offering to pay a higher price to expedite production.
Production followed a clear sequence: laser cutting → bending → welding → machining → coating (for carbon steel components).
While the initial products met all dimensional tolerances and functional requirements, they lacked aesthetic refinement. The drawings didn't specify appearance requirements, but we believed "qualified" wasn't sufficient—only "excellent" was acceptable.
We implemented an additional process: polishing and brushing on the stainless steel parts. This extra step smoothed welds and refined surfaces, resulting in flawless-looking products.
The client was highly satisfied with the final products, placing a second order just one week after receiving the initial shipment.
For the second order, we identified opportunities to optimize fabrication further. To enhance weld quality, we introduced robotic laser welding, which produces smooth, consistent seams that require no additional polishing.
This innovation saved time, reduced costs, and improved the final product appearance beyond the first order's quality.
Welding can even be conducted on the back side from internal
The first order was delivered via LCL ocean freight as requested by the customer.
For the second order, tight deadlines necessitated faster shipping. While air freight was significantly more expensive than sea freight, we developed an innovative solution: collaborating with a freight forwarder to consolidate our shipment with complementary goods from another client.
This approach required careful coordination to match our heavy but compact goods with lightweight but voluminous items. After persistent effort, we found the perfect consolidation opportunity. The result: the client paid only 15% more than sea freight costs but received their goods in just 5 days instead of the typical 30-day ocean transit time.
