Documents, not brochures.
Technical data sheets, safety data sheets, declarations of performance, certificates and installation guides — in the format a tender actually asks for.
Everything a submission needs, in one place.
Technical data sheets and catalogues are open. Certificates and declarations are open too — a buyer who has to register before seeing whether we hold ISO 9001 will not bother, and we would rather be checked than skipped.
Ten terms that cause most of the arguments.
If two quotes differ by a factor of two, the reason is usually in this list.
Coefficient of retroreflected luminance. The brightness a driver sees, in cd·lx⁻¹·m⁻². Always quoted with the two angles that produced it.
Angle between the light source and the surface normal. Grows as the sign gets closer and higher.
Angle between the light source and the viewer. Set by eye height and distance — small for a car, larger for a truck cab.
Cube-corner structure that reflects light back through three internal faces. Higher RA than glass beads; more sensitive to surface contamination.
Spherical lens with a reflective backing. Lower RA, wider tolerance of dirt and wear, cheaper.
US conspicuity marking for heavy vehicles. Two-inch alternating red and white, minimum 250 RA.
European equivalent, Class C for conspicuity. Different geometry, different mark, often the same film.
Older term, still used in some tender documents. Numerically similar to RA but not interchangeable without the geometry stated.
Conversion of the coating from liquid to solid. Under-cure is invisible at dispatch and obvious at year two.
Force needed to peel the liner. Too low and the roll unspools in the box; too high and the liner tears at the applicator.
