The whole finishes square on and filling the frame, in the single colour throughout configuration, shot level in flat overcast light against a plain wall so the proportion and the frame-to-glass ratio can be read without perspective.

Close detail of the meeting line at eye level in raking light, tight enough that the joint and the seal are legible, with the background thrown out of focus.
1:1
The hand-level detail: aged brass photographed in use on the ral 9005 matt black finish, close enough to show the surface texture and the fixing, with a hand on the handle for scale.

From inside the room looking out through the finishes, the unit open where it opens, late afternoon light on the floor, so the product is seen the way it is lived with rather than the way it is sold.

The finishes at dusk from outside, closed, the room lit behind the glass, so the finish and the glass line read against the light.

Description
Steel corrodes if the coating is wrong, so finish is a durability decision before it is a colour one. External frames are shot-blasted and hot-dip galvanised to BS EN ISO 1461 at 45 to 85 microns, then powder coated at 60 to 80 microns. Internal frames skip galvanising and take a zinc-rich primer. 213 RAL colours are available in matt, satin or textured, with different colours inside and out. Inland, that stack runs 25 years before recoating. Hand-waxed blackened steel is left uncoated and needs re-waxing every 12 months.
Specify it when
Decide this on durability first: anything external, any bathroom or pool room, and any address within 5 km of salt water needs galvanising under the colour, whatever the colour is.

1:1More in bespoke
Wide, dead-straight-on shot of a five-bay steel screen with central double doors and a top light in a bare plaster room, raking morning side light picking out the 25 mm sightlines and the shadow gaps at the mullions.

Configurations
Tight angled shot straight through two adjacent panes in one steel screen, clear on the left and reeded on the right, with a hand held flat behind the glass so the difference in distortion reads at a glance.

Glass
Hip-height detail of a monkey-tail handle and mortice escutcheon on a closed steel leaf, shallow depth of field, a thumb resting on the lever so the scale and the wear on the aged brass both read.

Hardware
Over-the-shoulder view of a specifier's desk: an A1 section drawing weighted flat at one corner, a laptop open on the same detail in DWG, and a 200 mm offcut of thermally broken steel section holding down the other edge of the sheet.
