Planks, gratings and stair treads for maximum fire protection in offshore, industrial and critical infrastructure environments.
See LHD® productsLHD® is a low-hole density grating designed for areas where fire safety, drainage, and slip resistance are critical.
Manufactured in carbon steel, stainless steel and aluminium, LHD® can be supplied in various widths, heights, lengths and profile combinations to match project requirements. Or planks are available either as welded modules for fast and efficient installation or as individual planks for subcontractors and on-site assembly.
Tested and approved by the Swedish research institute RISE for its fire-extinguishing and oil-draining properties, LHD® offers documented performance and reliable protection for demanding onshore, offshore and energy-sector environments.
With LHD®, you get a solution designed to withstand daily use without requiring extensive maintenance. This can reduce the need for ongoing repairs and make the solution easier to operate over time.
Designed for simple, efficient installation. This makes on-site work more manageable and can help speed up the installation process.
Designed for substations where fire safety, drainage, and slip resistance must go hand in hand. Its low void ratio restricts airflow, while the grating simultaneously drains leaking oil and provides a safe surface for those working at the facility.
LHD® combines high load-bearing capacity with efficient use of materials. This results in a strong and stable solution without unnecessary weight, making the grating easy to handle, install, and integrate into the project.
Available in different materials, allowing the material to be tailored to the project’s requirements for strength, weight, environmental considerations, and service life. This provides a flexible solution, whether the focus is on low weight, high load-bearing capacity, or enhanced corrosion resistance.
Tested and approved for its oil drainage and fire suppression properties. The low open area helps limit airflow, while the drainage design allows leaking oil to pass through safely.
A versatile solution for industrial applications, public areas and the energy sector, including transformer stations, substations and other technical facilities where reliable flooring, drainage and safety are essential.
Combines high strength with excellent corrosion resistance, making it the premium solution for harsh or exposed environments. It is particularly suited for offshore platforms, coastal installations, energy facilities, processing plants and areas where hygiene, weather resistance or aggressive conditions must be considered.
Lightweight, durable and corrosion-resistant, LHD® Aluminium is ideal for projects where low weight and easy handling are important. It is a strong choice for applications where reduced structural load and low maintenance are key priorities.
Designed for heavy-duty use, it provide steel is ideal where performance, load-bearing capacity and long service life are critical.
The low-hole density design is a key safety feature. Designed with 7 mm raised and depressed punched holes in 3 mm thick material, the profile provides a heel-friendly walking surface with strong slip resistance and very low visual transparency of just 3–5%.
As the airflow is carefully controlled with less than 5%, LHD® helps suppress flames while still allowing leaking oil, water and other liquids to drain away efficiently. This makes it particularly suitable for applications where fire-retardance and liquid drainage must work together, such as transformer stations, substations, power plants, offshore platforms, refineries and other energy-sector facilities.
LHD® is widely used in industrial and public applications where strength, safety and a clean visual appearance are required. In the energy sector, it is especially relevant for transformer substation flooring, heat shielding, maintenance platforms, access walkways and technical service areas where fire risk, oil leakage and operational safety are critical considerations.
