Straight Stairs
STRAIGHT STAIRCASE · STEEL STRINGER · LINEAR RUN
a custom metal staircase on a straight run, living floor to bedroom floor
A straight stair is a linear flight between two floors. The hall already has the run. You send that run and the finished-floor rise. We send shop drawings back.
DBM fabricates a straight steel staircase in our Guangdong workshop. We stand the flight on the shop floor, then pack a labelled flat-pack. Your local contractor installs.
A custom straight staircase — also custom straight stairs — follows one line between landings. Need to replace a staircase in an existing opening? Send that opening with the rise. We size the stringer to the hole. This is a factory flat-pack, not a retail kit.

Send rise and run. We reply with shop drawings.
VILLA & COUNTRY HOME
Villa owners often want the foyer to read as one straight line from the living floor to the bedroom floor. A center-beam stair with hardwood treads leaves both sides open. A box-stringer stair closes the risers and wraps the steel in hardwood.
Cable, glass, or wrought-iron infill can match the house. The wall can hide the stringer if you want a floating read.
NEW HOME BUILD
House plans often lock a straight hall before anyone picks the stair. We take rise and run from those plans.
A single center beam reads open. Two side stringers read more solid. Hardwood, steel-plate, or composite treads follow the rest of the interior.
APARTMENT & CONDO
A straight steel staircase with pan treads is a common read for a unit conversion or a split-level floor. Powder-coat or galvanized finish follows whether the stair shows or sits in a stairwell.
If one flight cannot cover the rise, we add a landing and a second run. Drawings follow the tread depth and headroom on your plan.
BATCH RENOVATION & MULTI-UNIT DEVELOPMENT
When the same straight flight repeats, stringer profile and tread count stay the same from floor to floor.
We pre-drill the connections and label the treads by floor. That is a factory pack to one drawing, not a DIY kit from a shelf.
Stringer on a Linear Run
A straight flight hangs from its stringer. Choose the beam first. Treads and the railing follow that choice.
| Product | Material | Style | Typical use |
|---|---|---|---|
| Monostringer Straight Stair | Powder-coated steel beam + hardwood treads | Center-beam, open-riser | Villa interiors, open foyers |
| Double-Stringer Straight Stair | Galvanized or powder-coated stringer pair + pan treads | Twin side stringers | Apartment stairwells, walk-ups |
| Box-Stringer Straight Stair | Closed steel box + full hardwood risers and treads | Closed-riser, hardwood wrap | Formal foyers, closed-riser homes |
| Floating Straight Stair | Wall-concealed stringer + cantilever treads | Open-riser, hidden support | Modern entries, wall-hidden support |
| Multi-Run Straight Stair Package | Repeated stringer pairs + landings between flights | Stacked flights with landings | Stacked floors, batch renovations |
A fabricated metal staircase on this page means we cut, weld, and finish the stringer in the shop. We trial-assemble it before it ships.
Rise, Run, and Landings
Rise is finished floor to finished floor. Run is the horizontal length the hall can spare. Both numbers set the stringer.
One flight needs enough run for the rise. If the hall is short, we break the stair with a landing and a second run. If even that will not fit, a spiral or a curved flight may use less length — compare those pages below.
Send those two numbers, plus a photo of the hall or the existing opening. We draw the layout. Your local engineer reviews the shop drawings.
From Shop Drawing to Labelled Crate
We draw first. Then we fabricate, stand the stair, take it down, and crate it.
Treads: hardwood for villas and new homes; pan or grate steel for stairwells; composite when you want less upkeep. Risers: open on a center beam or a floating profile; closed on a box-stringer. Finish: powder-coat on a visible steel beam; galvanized where the stairwell sees damp.
Railing: stainless cable, glass, wrought iron, or hardwood spindles — made with the stair so the finish can match. Code families on the drawings: IRC · IBC · AS 1657 · AS 1288 · NCC · CSA. Your local engineer carries them through permit. We do not stamp.
Crafted in our 4,500 m² Guangdong workshop. We do not handle on-site permitting or local installation. Shop drawings go to your local engineer and installer.

Frequently Asked Questions
Stringer type, short halls, and freight — the questions owners and contractors send before a drawing. If yours is not here, send rise and run through Request shop drawings.
What is the difference between a center-beam, twin-stringer, and box-stringer stair?
A center beam (monostringer) is one steel beam under the treads. Both sides stay open. Twin stringers run up the sides, and treads land between them — a common stairwell read. A box-stringer wraps a closed steel frame in hardwood risers and treads.
My hall is short. Will a straight stair still fit?
It depends on the rise. Tread depth and riser height on the drawing set how much run one flight needs. Send the rise and run you have. We return a straight-flight layout, or we show a landing, or we point you to a spiral or curved page if the hall is too short.
Can you replace a staircase in the same opening?
Yes, when the new flight must sit in the hole the old stair leaves. Send the opening size with the rise. We draw a stringer to that hole. This page is not a whole-home renovation guide — only the stair that goes in that opening.
Can a licensed engineer in my country stamp your drawings?
A licensed engineer in your country stamps the drawings. We do not stamp them. Shop drawings list IRC, IBC, AS 1657, AS 1288, NCC, and CSA for the United States, Australia, and Canada.
How is a straight stair packed for ocean freight?
We pack in flat-pack, photo-documented. We band the stringers together and stack the treads in stair-up order. Fixings go in a tagged box. A PDF assembly manual ships with the pack for your installer.
