Stainless steel grating is a type of metal grid structure widely used in industrial, commercial, and architectural applications due to its strength, corrosion resistance, and modern appearance. Whether used in walkways, platforms, drainage covers, or food processing environments, stainless steel grating provides a durable and low-maintenance solution where safety and cleanliness are key priorities.
In this article, we’ll cover everything you need to know about stainless steel grating—its types, materials, manufacturing process, benefits, and major applications.
Stainless steel grating consists of a series of bearing bars and cross bars that are welded or mechanically interlocked to form a rigid grid. The open grid structure allows water, air, light, and debris to pass through, making it ideal for environments that require ventilation or drainage.
Unlike carbon or mild steel grating, stainless steel grating is made from high-grade stainless steel, such as 304 or 316, offering superior corrosion resistance and aesthetic appeal.

Depending on the manufacturing method and application, stainless steel grating comes in several common types:
The most common type, where bearing bars are welded to cross bars at each intersection. Offers strong load-bearing capacity and is ideal for heavy-duty industrial applications.
Cross bars are mechanically pressed into notches in the bearing bars without welding. This type provides a clean, uniform appearance—popular in architectural and commercial settings.
Used for lighter duty applications. Round cross rods are swaged into notches in the bearing bars, offering both stability and economy.
The two most widely used grades in stainless steel grating are:
304 Stainless Steel: Good corrosion resistance, suitable for most indoor and outdoor applications. Commonly used in food processing, chemical plants, and drainage systems.
316 Stainless Steel: Contains molybdenum for enhanced resistance to chlorides and harsh environments. Preferred for marine, coastal, and industrial chemical exposure.
Stainless steel grating provides several distinct advantages over other materials:
Corrosion Resistance: Can withstand exposure to moisture, chemicals, and saltwater without rusting.
Long Service Life: High durability and minimal maintenance make it cost-effective in the long term.
Hygienic Surface: Easy to clean and resistant to bacterial growth—ideal for food and pharmaceutical industries.
Non-Slip Surface Options: Serrated bars can be added for better grip in slippery conditions.
Aesthetic Appeal: Polished or brushed finishes make it suitable for architectural uses.
Thanks to its superior performance, stainless steel grating is widely used in a variety of industries and applications:
Provides a strong, safe surface in factories, chemical plants, oil refineries, and power stations.
Allows for efficient water drainage while withstanding heavy pedestrian or vehicle loads.
Corrosion-resistant and hygienic—suitable for meatpacking plants, breweries, and commercial kitchens.
316-grade stainless steel is ideal for docks, ship decks, and offshore platforms.
Used in facades, stair treads, sunshades, and ventilation panels for its sleek and modern look.
While galvanized steel grating offers good corrosion resistance at a lower cost, stainless steel grating excels in environments with high humidity, chemical exposure, or hygiene requirements. It’s a preferred option when aesthetics, durability, and rust-resistance are critical.

How to Choose the Right Steel Grating? Learn about the different types and their benefits
Steel grating is a structural material widely used in industry, construction, municipal administration and other fields. Different types of steel grating have their own characteristics in terms of strength, corrosion resistance, load-bearing capacity and aesthetics.
HOT-SALE PRODUCT
Welded Steel Grating is a high-quality flooring and access material that consists of load -bearing bars and crossbars.
Standard steel grating, also known as Open Steel Grating , usually has a length ranging from 1000mm to 7500mm and a width ranging from 993 to 1000mm. Bearing Bars range from 20*3mm to 150*10mm. The surface is flat or serrated, and the surface treatment is galvanized, painted or untreated.
Press-Locked Bar Grating is a steel grating product that tightly locks the cross bars (typically shorter than the bearing bars) and bearing bars together using high-pressure mechanical equipment.
Shunbo pressure welded grating is used in various industrial fields, municipal engineering, construction and offshore drilling platforms, etc. Each intersection of the Bearing Bar and the Cross Bar is continuously welded to form an extremely stable and durable structure.
