The Four Main Types & Uses Of Grating for Flooring

When it comes to floor gratings, there are four main types, each having unique properties, making them suitable for various commercial applications.

1. Aluminium Grating

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.


  • Lightweight
  • Excellent corrosive properties
  • Fully recyclable
  • Aesthetic appeal
  • High strength to weight ratio
  • Non-toxic

Ideal Application Areas

  • Water treatment plants
  • Sewage and wastewater treatment plants
  • Marine superstructure applications
  • Any application near water or that has an aesthetic barrier near water.

2. Fibre Glass Grating

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.


  • High corrosion resistance properties
  • High slip resistance
  • Good flame resistance
  • Range of colours
  • Non-magnetic

Ideal Application Areas

  • Battery plants
  • Coal and iron ore industries
  • Wine and beverage manufacturing unit
  • National Park walkways.

3. Mild Steel Grating

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.


  • Robust
  • Easy customisation
  • Range of finishes
  • Anti-slip
  • Cost-effective

Ideal Application Areas

  • Safe walkways
  • Automotive industries
  • Manufacturing sites
  • Data centres
  • Plant and fan rooms that support machinery
  • Public areas like platforms at stadiums.

4. Stainless Steel Grating

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.


  • Aesthetic appeal
  • Robust
  • Excellent corrosion resistance
  • Anti-slip surfaces
  • Range of finishes
  • Endless customisation
  • Cost-effective

Ideal Application Areas

  • Power stations
  • Marine environment
  • Public spaces
  • Chemical plants.
