Industrial and security fencing is built from rigid galvanised steel systems, twin-wire mesh, palisade and narrow-aperture anti-climb mesh, chosen for strength, height and resistance to climbing and cutting rather than for looks. The panels are galvanised and powder-coated for a long perimeter life, and set on heavier posts and deeper foundations than a domestic fence….
Choosing a fence starts with the job it has to do, privacy, security, demarcation or architectural looks, and only then moves to the material and style: aluminium for light, rust-free, low-maintenance boundaries, and galvanised steel for rigid, high-security or industrial lines. Privacy comes from the panel style rather than the metal, exposure decides the corrosion…
Fence panels are installed by setting the posts first, plumb and in concrete below the local frost line, then fitting each panel or slat bay to the posts as you work along the line, checking level and spacing at every bay. The method is the same for a modular aluminium slat system and for galvanised…
Galvanised pipe is best cut with cold methods, a rotary pipe cutter, bandsaw or hacksaw, which leave a clean square end and little fume, after which the bare cut edge is re-protected with zinc-rich paint so the exposed steel does not rust. The two things that make galvanised pipe different from bare steel are that…
Steel products keep best when stored dry, off the ground and with air between them: galvanised steel packed tight and wet forms white rust, and bare steel rusts, so raising the stock on bearers, spacing items for air flow and letting water drain away prevents most storage damage. Good storage protects the value of the…
Galvanised profiles and pipe are the everyday structural members of outdoor and industrial construction: purlins and framing, fence systems and gates, agricultural and modular buildings, walkways and gratings, handrails and solar sub-frames, wherever steel must stay strong for decades without painting. Their appeal is simple: structural strength at a low cost, with corrosion protection built…
Galvanised steel can be welded, but the zinc coating must be handled with care: it gives off zinc oxide fume that causes metal fume fever, so the coating is removed from the weld zone, the work is ventilated, and the burnt area is re-coated with zinc-rich paint afterwards. Done properly, a galvanised part welds much…
Galvanised steel resists corrosion because its zinc coating works two ways at once: it seals the steel from air and water as a physical barrier, and it corrodes in place of the steel as a sacrificial layer, so even a scratched coating keeps protecting the metal underneath. How long that protection lasts depends on the…
Chequer plate is steel or aluminium plate with a raised anti-slip pattern rolled into one face, used for floors, walkways, stairs, ramps and vehicle beds wherever grip underfoot matters. The steel version is hot-rolled mild steel, usually S235JR, and the aluminium version is a lightweight, corrosion-resistant alternative. The raised diamond or teardrop pattern gives traction…
Black steel sheet is hot-rolled mild steel supplied flat, with the dark mill-scale surface that gives it its name, in forming grades DD11 to DD14 for pressing and bending, or structural grades S235 to S355 for load-bearing work. It is the everyday sheet of fabrication: economical, strong and easy to work, bend and weld, but…
