Carbon Steel Grating

Carbon steel grating is a heavy duty grating that can be used where open flooring is needed for air, light and heat transmission. It does not exhibit good corrosion resistance, so should not be used in applications that are exposed to corrosive elements.  The grating selection is based on load requirement, corrosion resistance, durability, and cost.

Carbon steel grating types available are:

  1. Welded – The carbon steel bars are resistance welded to create a rugged, one piece constructed panel.  This is the most popular of all grating types due to its strength, cost effective production, and ease of installation. 
  2. Press Locked – Press-Locked grating is manufactured using hydraulic pressure to lock notched bars together. It provides excellent lateral support and has a clean, smooth look. It is not able to support the weight of rolling loads.
  3. Close  Mesh – Close mesh grating has a tighter mesh than welded or press-locked grating.  The bars are closer together, providing a narrower opening in the grate. It is  suitable for applications requiring narrow spacing for aesthetic or functional reasons.
  4. Stair Tread – Welded steel stair treads are most widely used for their strength and ease of installation and are universally used in most industrial and commercial applications.

Surface Options Available:

  • Serrated
  • Grit
  • Painted


Carbon steel grating is used in applications that require strength and is typically used for platforms and walkways in chemical plants, oil rigs, and paper mills.  In addition to flooring, bar grating can be used to make drainage ditch covers, catwalks, stairway platforms and stair treads.

Fiberglass Grating

Fibergrate grating combines unmatched corrosion resistance with strength, long life and safety. It has been proven to deliver years of reliable service, even in the most demanding corrosive conditions – conditions which can cause conventional steel grating to deteriorate rapidly.  Fibergrate sets the standard for fiberglass grating.

O’Neal Steel carries two types of Fibergrate grating:

  1.  Molded – Molded grating is strong, sturdy and able to withstand the effects of corrosion. In addition, it is highly impact resistant.
  2. Pultruded – Pultruded grating is designed to handle high loads.  It reliable corrosion resistance and is a strong, durable product.
