Two flanges, one web, drawn on a 7×9 unit field. It was chosen because it can be cut from plate, cast into a mould, routed into a sign, embroidered onto a jacket and etched at 3mm without a single redraw.
The ratio is structural, not aesthetic — it is the profile of the section Halden has rolled since 1911.
Measured on all four sides. A fabricator can set it out with the mark itself as the gauge, without a manual.
Verified etched, laser-cut and embroidered. Below 3mm the web closes, so the wordmark is used alone.
On PPE the mark is solid graphite or solid white. Outlined versions fail the retroreflective test.
Halden is the brand; the division is a descriptor, never a logo of its own. Each carries a keyline colour used for wayfinding and document control — never for the mark itself.
Horizontal for documents and livery, stacked for plant signage, mark-only for cast and machined parts, safety orange for anything a person wears.
Concrete and graphite build every document and surface. Safety orange and caution yellow are regulated: they appear only where a standard requires them, so they never lose their meaning on site.
Signage and livery use the condensed cut because sign panels are narrow and the letters must stay large. Everything read at arm's length uses the standard grotesque. Mono carries anything a machine produced.
The identity is worn more often than it is read. Every application below was specified against a material and a standard before it was drawn.
Site signage is a legal instrument before it is a brand asset. These are drawn to the same stroke weight and corner radius as the logotype, so a Halden sign is recognisable before it is read.
The mark arrives like a press: fast, heavy, and it stops dead. Nothing in the system eases out slowly, because nothing on a plant floor does.
