A fence has to stand up to whatever the site puts against it: people trying to climb it, stock leaning on it and years of weather. Corona makes the steel parts behind five kinds of fence, from pales, rails and posts for palisade perimeters to tension bars, truss rods and fittings for chain-link, barbed wire arms for security topping, drop rods for gates and studded posts for farm fencing. Every part is made to the size and standard the buyer specifies.

Where it's used
Factories, substations, water works and rail yards need a boundary that is hard to climb and hard to get through. Across the UK, Ireland and much of the Commonwealth, that boundary is steel palisade, with thicker pales and taller bays where the risk is higher. Palisade Fence, Machine Bolt and Carriage Bolt cover it.
Chain-link surrounds most schools, tennis courts, car parks and warehouse yards in North America, and Australian chainwire and European simple-torsion mesh do the same job elsewhere. The mesh arrives on a roll. What keeps it upright and tight is the steelwork at the posts. Tension Bar, Truss Rod, Fence Fittings and Carriage Bolt cover it.
Storage yards, depots and plant compounds often need more than the height of the mesh they already have. Strands of barbed wire above the fence line add a clear deterrent without rebuilding what is standing. Barbed Wire Arm and Fence Fittings cover it.
Paddocks for cattle, sheep and horses, and long rural boundaries, are fenced with wire on driven steel posts across North America, Australia and New Zealand. A line of steel posts goes in quickly and needs no concrete. Fence Post and Fence Fittings cover it.
Every fence line needs a way through for vehicles, people or stock. On double gates, one leaf has to stay put while the other swings, whatever the wind is doing. Gate Drop Rod, Fence Fittings and Carriage Bolt cover it.
