Custom Steel Grating Fabrication
From a measured opening or a steelwork drawing to banded, coated, marked panels in eight stages.
Almost nothing that leaves this plant is a stock panel. A buyer sends an opening, a drawing or a photograph of a failed cover, and what goes back is a 3D model of the panel, its frame and the opening it has to sit in. Agreeing that model is what stops the two failures that cost the most: a panel that will not drop in, and a panel that drops in but was never strong enough for what crosses it.
Custom Steel Grating Fabrication In 8 Steps
Drawing And 3D Model
A grating that is wrong on paper is wrong in steel, and steel is expensive to be wrong in.
The design team models the panel, the frame and the opening it has to sit in before any bar is cut, so bearing bar pitch, panel division and frame clearance are agreed in a drawing rather than discovered on site.
Material Selection
Carbon steel and stainless steel fail in completely different places.
Carbon steel with a hot-dip galvanized coat for general traffic and drainage, stainless steel with acid passivation where washdown, chloride or food-grade cleaning is involved. Aluminium alloy is produced where weight is the constraint.
Cutting And Stamping
Bar ends that are not square never sit flat in a frame.
Bearing bar and cross bar stock is cut and stamped on the plant’s laser cutting and stamping equipment, which is also what makes serrated and toothed edges repeatable across a batch.
Pressure Welding Or Press Locking
The joint between bearing bar and cross bar is the whole strength of a panel.
Welded panels are produced on the automatic pressure welding line. Press locked panels are assembled by forcing the cross bar into the bearing bar under pressure, which is what gives a flush top surface without a weld bead.
Framing And Fabrication
Most grating complaints are about edges, not about the mesh.
Banding bar, end plates, hooks, hinges, lifting handles and cut-outs for pipework are fabricated to the drawing, so the panel arrives as a finished cover rather than as a sheet to be trimmed on site.
Surface Treatment
The coating decides how many winters a panel survives.
Hot-dip galvanizing, electroplated galvanizing, painting or acid passivation, chosen against the environment the panel will live in rather than against the invoice.
Inspection Before Packing
A panel that does not drop into its frame is scrap once it is in a container.
Panels are checked against the drawing for size, squareness, bar pitch and coating finish before they are banded and stacked.
Packing And Export
Grating is heavy, sharp and easy to damage in transit.
Panels are stacked flat, banded and packed for sea freight, which is the route most of this plant’s output takes.
