Safelock is the most slip resistant steel flooring in the Lionweld Kennedy range. Due to the double serration, Safelock is used in the most extreme conditions where slip resistance is vital such as oil rigs or other areas where lubricants are regularly used.

Safelock load bearing bars are machine serrated as standard to provide optimum slip resistance. and to enable machine serrations in both directions (double serrated), the transverse bars are made from 13mm x 13mm x 3mm inverted angles and then pressure locked into the load bearing bars.

Ball Proof Requirements

The British standard requires grating to be 35mm or 20mm ball proof, unless there is no risk of people passing beneath the open mesh walkway.  Click here to read our guidance on selecting the correct ball proof requirement for your project.

Frictional Fixings

Frictional fixings can be used to secure steel grating to the supporting steel work.

The fixing assembly consists of a universal bottom clip (Type 5), M8 hex nut, bolt and a top clip.

Positive fixings

In areas where the grating may be subject to vibration or lateral forces, it may be advisable to utilise a positive fixing clip.

Building Information Modelling (BIM)

Following the government mandate on BIM level 2 requirements throughout the supply chain for all government funded projects, Lionweld Kennedy have built on our existing processes to become fully BIM level 2 compliant. Our internal processes are aligned with the requirements of PAS1192-2:2013 to ensure full BIM compliance and ensure we are prepared for fully collaborative working practices in line with specific client requirements. Using our primary BIM authoring software Tekla Structures, which is aligned to our in house manufacturing processes we have developed our comprehensive BIM object library available for download.
