In structural steelwork and composite flooring construction, fixing methods can sometimes be treated as a minor detail. In reality, they can affect installation speed, structural integrity, long-term durability and, most importantly, worker health.

One particular risk arises when drilling through steel decking profiles into the concrete slab above. This process releases respirable crystalline silica dust from the hardened concrete. These microscopic particles can become airborne and, if inhaled, penetrate deep into the lungs. Prolonged exposure is associated with serious and irreversible health conditions, including silicosis, chronic obstructive pulmonary disease and lung cancer.

Lindapter decking fixings are specifically designed to avoid this risk.

The problems caused by drilling through decking

Traditional drilling through steel decking into concrete introduces several challenges.

It exposes workers to silica dust, which cannot be addressed simply through surface cleaning. It also increases labour requirements and programme time, particularly when working around live services or in areas with restricted access.

Drilling can damage protective coatings on the decking profile, potentially increasing the risk of corrosion over time. It can also introduce more complicated safety procedures, including permits, risk assessments and restrictions that may slow progress.

Removing the need to drill into concrete

Lindapter decking fixings are designed to work with the existing geometry of the decking profile. They locate within the dovetail re-entrant channels of popular composite decking systems and clamp securely without penetrating the decking surface.

This means no on-site drilling or welding is required. Installation is faster, safer and less disruptive, while protective coatings and the integrity of the deck remain intact. Most importantly, exposure to silica dust is eliminated at source.

Why this matters on site

Drilling through decking into concrete is not only a health issue. It also increases installation time, requires dust suppression and extraction controls, and introduces noise and vibration.

There is also a risk of misalignment or rework, damage to protective finishes, and the need for additional approvals and safety procedures.

Clamp-based decking fixings provide secure, tested attachment points for building services and secondary steelwork while preserving the integrity of the deck.

For projects operating under strict health and safety controls, or those looking to reduce long-term occupational exposure risks, removing the need to drill into concrete represents a meaningful improvement.

Supporting best practice through training

To help contractors, engineers and specifiers understand the technical and practical benefits of these solutions, Lindapter has produced a dedicated series of training videos.

The videos cover what decking fixings are and how they work, compatibility with different decking profiles, correct installation methods, common on-site best practice, and the advantages of avoiding drilling into the concrete slab.

The first videos focus on the TR60, MF and MW2 decking fixings. Each demonstrates practical installation methods and explains how the fixing engages with the decking profile without penetrating the slab above.

These videos provide a clear and accessible starting point for teams looking to modernise their approach.

From video learning to accredited CPD

While the videos introduce the main principles, some organisations require a deeper technical understanding, particularly when preparing specifications, assessing risk or choosing compliant fixing methods.

Lindapter’s accredited Continuing Professional Development sessions are available online or face to face. They cover structural and load considerations, decking profile compatibility and limitations, compliance and testing data, the health and safety implications of different fixing methods, best-practice specification strategies, and risk reduction by eliminating concrete drilling.

These sessions are designed for consultants, designers, contractors and site teams seeking greater technical confidence and better-informed decision-making.

Better decisions at connection level can lead to better outcomes across the entire project.
