Straight Stairs
STRAIGHT STAIRCASE · MONO-STRINGER · BOX-STRINGER · FLOATING
a clean line from the living level to the bedroom level, hardwood underfoot
Straight-flight stairs are the clean, deliberate choice when the floor plan accepts a single run between two landings. Picture a modern foyer with sunlight crossing each tread, hardwood underfoot, the flight running clear from one level to the next. We fabricate straight metal staircases and straight stair kits for villa interiors, new-home builds, apartment and condo unit conversions, and batch-renovation packages. Send the finished-floor-to-finished-floor rise and the run length you have available. We return a single-run or multi-run stringer layout sized to drop in.
VILLA & COUNTRY HOME
Private estates and country residences where the stair runs straight as a deliberate design choice. The line from living level to bedroom level reads as a single architectural gesture. Statement monostringer flights with hardwood treads, box-stringer flights wrapped in matched veneer, or floating straight stairs where the wall hides the support. Coordinated with cable, frameless glass, or wrought-iron handrails and recessed tread lighting where the architect calls for it.
NEW HOME BUILD
Two-storey new builds, basement-to-main-floor flights, and modern open-plan interiors planned in from the architect's first drawing set. Two products dominate here. The monostringer runs a single center beam with hardwood treads and an open-riser look for a modern interior. The closed-stringer traditional stair runs two side stringers with full risers, wrapped in hardwood. Both ship with a hardwood, steel-plate, or composite tread option to match the rest of the interior.
APARTMENT & CONDO
Apartment interiors, condo unit conversions, loft conversions, and split-level unit flights. Straight steel staircases and pan-tread straight metal staircases ship in galvanized or powder-coated finishes. Drawings are sized to the tread depth and headroom referenced on the architect's plan. Straight single flight steel staircase details lead the spec sheet: two stringers, pan or grate treads, intermediate landing if the rise exceeds the single-run threshold.
BATCH RENOVATION & MULTI-UNIT DEVELOPMENT
When the same straight stair repeats across multi-unit renovations, multi-level apartment buildings, or stacked stairwell flights — same stringer, same tread count, repeated floor to floor. We pre-drill the stringer connections and label the treads by floor level. The bundle ships on a single pallet per stairwell. The same template lands cleanly in each unit without sorting parts on site.
Straight Staircase — Range Overview

|---|---|---|---|
| Monostringer Straight Stair | Powder-coated steel beam + hardwood treads | Center-beam, open-riser | Residential interiors, loft conversions |
| Double-Stringer Straight Stair | Galvanized or powder-coated stringer pair + pan treads | Twin side stringers | Apartment stairwells, multi-unit walk-ups |
| Box-Stringer Straight Stair | Closed steel box + full hardwood risers and treads | Traditional closed-riser | Villa foyers, formal new-home interiors |
| Floating Straight Stair | Wall-concealed stringer + cantilever treads | Open-riser, hidden support | Modern entries, statement walls |
| Multi-Run Straight Stair Package | Repeated stringer pairs + intermediate landings | Stacked-flight with landings | Multi-level apartment buildings, batch renovations |
About Our Straight Staircase Range
A straight staircase is a single-direction flight between two landings. We build it in mono-stringer, double-stringer, box-stringer, or floating profile depending on the look the floor plan calls for. Homeowners buy straight stairs when they already have the floor plan and just need the stair to land cleanly inside the run-length they have. The architect, designer, or contractor coordinates the install. Most enquiries here are villa and new-home owners fitting a monostringer between the living level and the bedroom level. Condo owners specify a straight single flight steel staircase for a unit conversion. Renovation owners order a multi-run package for a multi-level apartment building, and batch-renovation owners run repeat flights across a multi-unit development. The factory rarely ships a one-off straight stair. Orders almost always repeat the same stringer profile, treads, and connection detail across multiple flights — exactly where the kit format pays off.
Material choices on a straight stair run track the use case. Apartment stairwell and multi-unit builds run double-stringer steel with pan or open-grate treads. Choose hot-dip galvanized where the run sees damp, powder-coated where the stair is visible. Villa and new-home interior builds run hardwood treads on either a monostringer or box-stringer frame. The riser stays open or closed depending on whether you want a modern or traditional read. Floating straight stairs hide the structural stringer inside a wall pocket so the tread reads as cantilevered hardwood. Railings on every format pair with aluminum top-rail, stainless cable infill, frameless glass panels, wrought-iron balusters, or hardwood spindles. All come from the same factory so the finish schedule matches the stair.
Designed in our Guangdong studio and crafted in our 4,500 m² workshop. Each stringer pair is trial-assembled flat on the workshop floor for fit-up and tread squareness, then disassembled and packed by floor level. On-site install and local permit stamping run through your contractor and licensed engineer. We hand off the drawings and the labelled kit.

How to Spec a Straight Staircase for Your Project
The owner view: what to measure, what to send, and how to settle the stringer profile before we draw.
- Measure the rise. Finished-floor-to-finished-floor — from the lower-level floor surface up to the upper-level floor surface.
- Measure the run length. The horizontal distance you can give the stair. If you do not have enough run for a single flight, a multi-run package with intermediate landings is the answer.
- Decide the stringer profile. Mono-stringer = single center beam, modern interior. Double-stringer = side stringers, common for apartment stairwells. Box-stringer = closed traditional read with full hardwood risers. Floating = stringer hidden in a wall pocket.
- Choose the tread material. Hardwood for villa and new-home; pan or grate steel for stairwell and walk-up; composite where low maintenance is the priority.
- Tell us how many flights repeat. A single stair is one quote. Repeat flights across a multi-storey walk-up or batch renovation is where pre-drilled stringers and labelled treads pay off.
- Send it through. We return a stringer layout, landing positions, and a code-reference list. Your local engineer signs off and the kit lands cleanly floor by floor.
Frequently Asked Questions
Answers below cover the stringer choice, multi-run packaging, and freight questions owners and contractors ask before ordering. If yours is not here, send the rise and run through Request a Drawing Review.
Can you supply a multi-run straight-stair package for a multi-storey walk-up?
Yes — multi-run packages with repeating stringers, intermediate landings, and labelled tread sets are a regular run for us. Send the floor-to-floor rise and the number of stories. We draw the stringer break, landing positions, and pre-drilled connection points before fabrication.
What's the difference between a single-stringer (monostringer), double-stringer, and box-stringer build?
Monostringer runs a single steel beam down the center under the treads — open both sides, modern look, hardwood treads visible from below. Double-stringer runs two steel beams up the sides, treads land between them — the common choice for apartment stairwells and multi-unit flights. Box-stringer is a closed steel frame wrapped in hardwood riser and tread panels — the traditional residential look with full risers between treads.
My floor plan has limited run length. Will a straight stair still fit?
It depends on the rise. Code-referenced tread depth and riser height set the minimum run length for a given floor height. Send the rise and run you have. We check the geometry and either return a straight-flight layout or recommend a stair format with a landing or turn that fits the footprint.
Can your drawings be stamped by a licensed engineer in my country?
Yes. Shop drawings reference the code families for the United States, Australia, and Canada (IRC, IBC, AS 1657, AS 1288, NCC, CSA). Final stamping is handled by a licensed engineer in your jurisdiction through our partner network or yours.
How is a multi-run stair package crated for ocean freight?
Each stairwell ships as a labelled bundle — stringers banded together, treads pallet-stacked in floor-level order, fixings boxed and tagged. Photo-documented packing protects every component through ocean freight to your job site, and a PDF assembly manual ships with the package.
