Stainless steel grating is a versatile and durable solution for various industrial and commercial applications, providing exceptional corrosion resistance and hygiene properties. Made from high-quality stainless steel, this grating features an open grid design for strength, stability, and efficient drainage. It is commonly used in food processing plants, chemical facilities, and marine environments.

Available in 304 and 316 stainless steel grades, this grating caters to specific project requirements. Both grades offer excellent resistance to chemicals and atmospheric conditions, with 316 stainless steel providing enhanced corrosion resistance due to added molybdenum. Manufactured in styles such as welded, swage-locked, or press-locked, and customizable in size and load capacity, stainless steel grating meets the unique demands of any project.
We started our business with one simple goal in mind: to provide high-quality stainless steel products at the most competitive prices with the best service.
SUNJ GRATING LIMITED is one of the first companies in China manufacturing stainless steel gratings. We have many years of experience in the industry and our products are now used all over the world, in a wide variety of applications.
Welded stainless steel gratings are made of bearing bars and cross bars. The bearing bar is the main load-bearing component of the grating. It is available in a variety of thicknesses and depths. The crossbar is the secondary load-bearing component of the grating, and it is available in a variety of thicknesses. The two types of bars are joined together using welding, which results in a strong and rigid joint.
Press-locked stainless gratings are made of bearing bars and cross bars. The bearing bar is the main load-bearing component of the grating. It is available in a variety of thicknesses and depths. The crossbar is the secondary load-bearing component of the grating, and it is available in a variety of thicknesses. To join the two types of bars together, they are pressed into each other using a high-pressure process. This results in a strong and rigid joint.
Welding is ideal for permanent installations, while mechanical fasteners are a good option for when the grating needs to be removable or welding is not possible. For pedestrian applications, the minimum weld pattern to the right also serves as a guide for minimum fastener spacing. However, for vehicular applications, additional welding, size, and spacing may be required, as determined by the specifying authority.
Our saddle clips are made from steel, stainless steel, or aluminum and are suitable for use in installations where grating may need to be removed. In certain instances, it may be necessary to cut cross bars to accommodate fastener clearance during installation. Typically, saddle clips will be positioned in the same location as the welds unless specified otherwise. The fasteners have a diameter of 1/4 inch (6.4 mm).
Weld lugs are utilized for installations where the grating may require removal. These lugs will be positioned in the same location as the welds unless otherwise indicated. The fasteners used for weld lugs have a diameter of 1/4 inch (6.4 mm).
The first step is to select the appropriate material for the gratings. GI-RO technique offers different constructions of grating, each with its advantages. After deciding which structure to use, the materials are select. The most common materials used are stainless steel and aluminum.
The material is then tensioned to create a tight, even surface. It helps if the surface is not entirely flat but has a slight curvature. Avoiding any distortion in the wavefront and ensuring that the grating is flat is crucial. Stainless steel is tensioned using either a jig or a template.
Acid cleaned, brushed, or blasted &#; the surface of the gratings can be adapted to the customer&#;s needs. Stainless steel gratings are usually acid-cleaned, which gives them a bright and shiny surface. The gratings can be blasted or brushed if a different surface finish is required.
The gratings are then welded to the crossbars. By using a TIG welder, it is possible to create very small and precise welds. The welder has a special Argon gas protection, which prevents the formation of oxides on the weld.
After the gratings are welded to the crossbars, they need to be fixed. To fix the gratings, they are welded or screwed to the supporting structure. In this way, the gratings are securely fastened and cannot be removed without damaging them.

The gratings are now ready to be used! They can deliver in either sheets or ready-to-install panels. If the customer needs a specific size or shape, the GI-RO technique can also cut the gratings to order.
When it comes to floor gratings, there are four main types, each having unique properties, making them suitable for various commercial applications.
Aluminium gratings are well known for their lightweight, resilient, and corrosion resistance properties, which make them ideal choices for various industrial and architectural applications. Though aluminium gratings are lightweight, they have an unmatched strength-to-weight ratio and aesthetic appeal.
Due to their aesthetic appeal, aluminium gratings are used widely in architectural applications, such as facades, sunscreens, vents, fountains, ceiling tiles, fencing, walkways, and entranceways.
Aluminium gratings are also incredibly durable. This means they avoid signs of wear or decay because of their corrosion and rust resistance properties. Therefore, they are easy to maintain and save maintenance costs in the long run. Aluminium gratings are also non-toxic as they do not absorb bacteria-sustaining particles and are easily recyclable, making them suitable for circular design.
Fibreglass gratings (FRP) are modern floor grating solution that are more resilient than steel and aluminium gratings and have high load capacity, making them yet another ideal choice for industrial floor grating applications.
They have a very high resistance to corrosive liquids, chemicals, and saltwater. These characteristics make FRP gratings the most suitable choice for areas that need specific chemical resistance, with a variety of resin types available depending on the application. Since they are non-magnetic, they are also ideal for application areas sensitive to magnetic fields.
FRP gratings also come with standard anti-slip coatings and are available in various colours, including green, dark grey or yellow, to suit your specific needs. FRP is also very low maintenance product which doesn&#;t rely on constant upkeep to look tidy.
Mild steel gratings are the most flexible and economical grating choice as they can be customised in endless ways. They can be made in different profile sizes and thicknesses according to your unique requirements. Mild steel gratings also give you the flexibility to finish in different ways, including hot-dip galvanised, painted, powder-coated, and bitumen coated.
Hot-dip galvanised mild steel gratings, in particular, are robust and have a longer design life. Hence, they are used in a variety of pedestrian and screening applications. Weldlok Forgebar mild steel grating surfaces also allows the passage of light, air, and water, making them extremely multipurpose.
Mild steel gratings are most commonly used for fixed platforms, walkways, stairways, public areas and industrial applications.
Stainless steel gratings are a popular low-maintenance floor grating option. They are versatile and have excellent tensile strength and great aesthetic appeal, blending strength, durability, and aesthetics.
Just like mild steel gratings, stainless steel gratings are easily customised into various sizes, thicknesses, and spacings. They can also be finished with various surfaces and anti-slip finishes, including serrated edge flat bar and quartz grit. Stainless steel gratings are also excellent choices in areas where corrosion and rusting are of concern.
