Stainless Steel Grating Factory Direct | 304/316L Grades | Electro-Polished Mirror Finish | Food & Pharmaceutical Grade Cleanroom Platforms
In corrosive environments or projects with stringent hygiene requirements, ordinary carbon steel grating—even hot-dip galvanized—struggles to meet long-term service demands. Rust, contamination, frequent replacement—are these issues plaguing your project?
Stainless steel grating is the ultimate solution.
With 15 years of expertise in stainless steel deep processing, we operate fully automated resistance pressure welding production lines and electro-polishing surface treatment workshops. From 301 to 316L, from industrial platforms to five-star hotel ceilings, we deliver rust-free, maintenance-free, timeless premium grating solutions.
Why Choose Stainless Steel? Why Choose Us?
1. Material is King: Choose the Right Stainless Steel, 50 Years Without Corrosion
The core value of stainless steel grating lies in the material itself. We strictly select prime quality materials from TISCO and Baosteel, rejecting all reclaimed scrap to ensure stable chemical composition:
| Grade | Characteristics | Application Scenarios |
| 304 Stainless Steel | The most widely used austenitic stainless steel, offering excellent comprehensive corrosion resistance. Combines good formability and weldability—the most cost-effective choice. | Food processing, pharmaceutical workshops, general chemical plants |
| 316L Stainless Steel | Contains molybdenum (Mo), providing corrosion resistance to chlorides far exceeding 304—known as “marine grade steel.” Lower carbon content ensures superior resistance to intergranular corrosion after welding. | Offshore platforms, offshore wind power, coastal construction, pharmaceuticals, desalination plants, high-corrosion environments |
| 310S / 2507 Duplex Steel | For extreme conditions such as ultra-high temperature furnaces, high-concentration acids and alkalis—we offer higher-grade special stainless steel customization. | Ultra-high temperature, extreme chemical environments |
2. Two Premium Processes, Meeting Diverse Load Requirements
We offer two mainstream stainless steel grating manufacturing processes, precisely matched to your project needs:
| Process Type | Welded Type | Press-Locked Type (Insertion Type) |
| Manufacturing Method | High-pressure resistance welding machines weld cross bars into bearing bars—strong welds, high automation | Bars are slotted, then cross bars inserted and press-locked—no welding required |
| Product Features | Strong welds, smooth surface, high production efficiency—ideal for standard loads in large platforms and walkways | Lightweight,exquisite structure,precise assembly, no weld marks—ideal for architectural decoration, ceilings, grille windows |
| Recommended Scenarios | Industrial platforms, maintenance walkways, stair treads | Commercial building ceilings, ventilation shafts, interior/exterior decoration, advertising signage |
3. Surface Treatment: Beyond Corrosion Protection—Aesthetic Presentation
After welding, stainless steel develops oxidation coloring (bluish/yellowish) due to high heat—while not affecting function, it impacts appearance and corrosion resistance. We provide professional-grade surface treatments:
| Treatment | Process | Characteristics | Application Scenarios |
| Pickling & Passivation | Removes welding oxide layer, forms dense passivation film | Restores natural stainless steel color while enhancing corrosion resistance—uniform matte silver-gray finish | Industrial applications, cost-effective solutions |
| Electro-Polishing | Electrochemical process removes microscopic burrs and irregularities | Achieves mirror-like brightness, extremely high smoothness—no dirt accumulation, easy cleaning, exceptional visual effect | Food/pharmaceutical, high-end architectural projects |
Professional Note: Over 90% of stainless steel grating is custom-made. Whether industrial platforms or design projects, we deliver inspection-free precision fabrication according to your drawings.

How to Select the Right Stainless Steel Grating for Your Project
Step 1: Determine Application Environment
| Environment | Recommended Grade |
| Indoor dry environments, general food contact | 304 Stainless Steel |
| Coastal outdoor, salt-laden humidity, chemical contact | 316L Stainless Steel |
| Ultra-high load, vibration load | Increase bar thickness or select I-bar profile |
