Barclay & Mathieson supplies a comprehensive range of open steel flooring systems, providing strong, durable and slip-resistant surfaces for industrial walkways, platforms and access routes. Designed to perform in demanding environments, our open steel flooring offers excellent versatility, load-bearing capacity and slip resistance.
Our range includes 41/100 aperture (utility) open grid grating, 20mm and 35mm ball proof grating, and press locked grating, with correct product specification dependent on specific project requirements.
Open steel flooring is widely used across industrial, commercial and infrastructure environments, including:

Galvanised open grid flooring provides a strong, practical and cost-effective solution for walkways, platforms and service trenches where drainage or ventilation are required. Manufactured to withstand regular foot traffic and light machinery, this flooring performs reliably in both wet and dry conditions.
The hot-dip galvanised finish protects against corrosion, extending service life and reducing maintenance requirements in exposed or demanding environments such as water treatment plants, engineering workshops and warehouse facilities.
Open grid flooring offers good slip resistance and minimal cleaning requirements, making it a popular choice across many sectors. It is typically specified where there is no risk of personnel working beneath the walkway or platform.
Key characteristics include a robust open mesh design, 6mm twisted transverse bars welded for secure alignment, and a high strength-to-weight ratio for efficient handling and installation.
Load Tables
Ball proof grating is specified where there is a risk of objects falling from a walkway or platform onto areas below. The size of the apertures is controlled to prevent the passage of a defined sphere diameter, helping to protect people, equipment and working areas.
20mm Ball Proof Grating
20mm ball proof flooring is used where walkways or platforms are positioned above permanent working areas or machinery. The aperture design prevents the passage of a 20mm diameter sphere, reducing the risk of tools or components falling onto personnel below. Typical applications include production lines and plant rooms.
35mm Ball Proof Grating
35mm ball proof flooring is intended for areas where people pass beneath occasionally rather than continuously. It prevents the passage of a 35mm diameter sphere and is commonly used for maintenance access routes, industrial plants, unmanned substations and data centres where controlled access is in place.

Press locked (pressure locked) steel grating offers a clean, rigid and visually uniform solution for flooring, fencing, infill panels and covers in industrial, civil and commercial buildings. The grating is manufactured by mechanically pressing cross bars into load-bearing bars, creating a strong and stable panel with excellent load performance.
One of the key advantages of press locked grating is that it can be manufactured to precise length and width dimensions, resulting in minimal scrap or wastage, and making it ideal for bespoke layouts.
Press locked grating is available in a range of materials to suit different environments, including:
