304 vs. 316 Stainless Steel Grating
| Material | Corrosion resistance | Recommended environment | Purchasing consideration |
|---|
| 304 | Good resistance to general moisture, cleaning chemicals and many industrial environments | Indoor processing areas, commercial buildings, general drainage and freshwater applications | More economical than 316 for environments without heavy chloride exposure |
| 304L | Similar general corrosion resistance to 304, with lower carbon content | Fabricated and welded assemblies where project specifications require a low-carbon grade | Commonly considered when welding performance and corrosion around welded areas are important |
| 316 | Better resistance to chloride exposure, pitting and many chemicals | Coastal areas, marine facilities, chemical plants, wastewater treatment and outdoor drainage | Higher initial cost but more suitable for aggressive environments |
| 316L | Low-carbon version of 316 | Welded marine, chemical, food-processing and hygienic applications | Suitable when both chloride resistance and extensive welding are involved |
For Singapore projects, material selection should consider tropical humidity, frequent rainfall, coastal exposure, cleaning chemicals and the concentration of chlorides around the installation area.
Choose 304 or 304L for general indoor and controlled environments without significant chloride exposure.
Choose 316 or 316L for coastal, marine, chemical, wastewater and chloride-exposed environments.
Confirm the actual chemical concentration, temperature, cleaning process and expected service life before final selection.

Welded vs. Press-Locked Stainless Steel Grating
| Comparison | Welded grating | Press-locked grating |
|---|
| Construction | Cross bars are welded to the bearing bars | Cross bars are mechanically pressed into the bearing bars |
| Appearance | Industrial and functional | Uniform and architectural |
| Rigidity | Suitable for demanding industrial use | Suitable for controlled-load and appearance-sensitive applications |
| Typical applications | Platforms, walkways, plants and equipment access | Building entrances, façades, public areas and decorative flooring |
| Surface options | Smooth or serrated | Smooth or serrated, subject to design |
| Custom fabrication | Cut-outs, banding, framing and shaped panels | Custom mesh patterns, panel sizes and framing |
| Selection priority | Load, span, environment and durability | Appearance, mesh alignment, load and architectural requirements |
Final construction should be selected according to the clear support span, load condition, bearing-bar direction and project drawings.

| Coastal and marine projects | 316 or 316L, smooth or serrated according to slip risk | Salt exposure, immersion, splash zone and maintenance interval |
| Wastewater treatment | 316 stainless steel with serrated surface where wet access is expected | Chemical exposure, span, pedestrian load and fixing method |
| Industrial platforms | Welded grating selected by clear span and design load | Uniform load, concentrated load, support layout and deflection limit |
| Outdoor walkways | Serrated 304 or 316 depending on corrosion level | Rain exposure, pedestrian traffic, span and fastening |
| Drainage channels | Stainless steel drain or trench grating with matching frame | Clear opening, trench width, drainage capacity and traffic class |
| Stair treads | Serrated grating with side plates and nosing | Tread width, depth, fixing holes, nosing and stair layout |
| Architectural projects | Press-locked grating with uniform mesh and selected finish | Appearance, mesh alignment, finish, fixing concealment and load |
| Vehicle-access drainage | Heavy-duty grating designed according to wheel load | Wheel contact area, axle load, traffic direction, span and deflection |

FAQ
What is the difference between SS304 and SS316 stainless steel grating?
SS304 is suitable for general environments, while SS316 provides better corrosion resistance for marine and chemical applications.
Can stainless steel grating be customized?
Yes. We can customize dimensions, spacing, surface type, and fabrication according to project requirements.
Is stainless steel grating suitable for outdoor use?
Yes. Stainless steel grating is commonly used outdoors because of its corrosion resistance and durability.
Do you supply stainless steel grating for wholesale orders?
Yes. Canri supports bulk supply, distributor orders, and engineering project requirements.
