Work out how much stair nosing you need, what it costs and how to cut it, for every Floorsafe range: aluminium, recessed, fibreglass, PVC rubber and industrial metal. Then use the guides below to pick the right profile and check the standards that apply to your stairs.
Choose a range and profile, then enter the number of steps and the width for each stair size. We’ll work out the total metres, how many full lengths to order (allowing for saw cuts) and compare that with having us cut every piece to size.

Check colour and contrast on your own stairs
Order our free stair nosing sample pack before you buy, so you can hold each insert colour against your tread.
Choose a 10mm profile for public and commercial stairs that must meet AS1428.1, a deeper profile for worn edges and heavy traffic, and carborundum or fibreglass for outdoor stairs.
| Range | What it is | Best for | AS1428.1 recommendations |
|---|---|---|---|
| Aluminium | Extruded aluminium with a 50mm rubber, carborundum or fine line insert | Offices, schools, healthcare, apartments | RCF10, RCF10BLK |
| Recessed aluminium | Aluminium with carborundum inserts, set into a rebate so it sits flush | New builds and a flush, architectural finish | RNR10, RC21BLK |
| Fibreglass | FRP with a fully gritted surface. Won’t rust or rot | Outdoor, coastal, industrial, timber decks | FG10 nosing, FG50 strip |
| PVC rubber | Soft PVC with a serrated top, 28 × 60mm | Residential stairs, internal use only | – |
| Industrial metal | Galvanised steel angle with a heavy-duty anti-slip coating | Plant rooms, car parks, fire stairs, heavy traffic | RMN1050, RMN1075 |

Three standards cover the majority of stair nosing requirements. Always confirm what applies to your building or project with your certifier or access consultant.
AS4586 rates surfaces from P0 to P5 using the wet pendulum test. The higher the number, the more grip.
Covers stairs in factories, plant rooms and other industrial workplaces. Our 30mm fibreglass nosing (FG30) meets AS1657, and its deeper face also covers worn or chipped edges.
NCC 2022 Amendment 2 adopted AS1428.1:2021 from 29 July 2025. NCC 2025 was released on 1 May 2026 and each state sets its own start date: Victoria from 1 May 2026, and NSW, Queensland and South Australia from 1 May 2027.
Yes. Enter the number of steps and width for each size on a separate line. Add more stair sizes as needed.
It depends on your stair widths. Full lengths are usually cheaper when your widths divide neatly into a length, for example three 1200mm steps from one 3620mm length. Cut to size often wins when widths leave big offcuts, and there’s nothing to cut on site. Keep delivery in mind too: shipping full lengths is generally more expensive than shipping smaller cut-to-size pieces, because full lengths are oversize. The calculator ONLY compares both product prices and flags the lowest.
Every saw cut removes a sliver of material, so a 3620mm length won’t give you three pieces of exactly 1206mm. We allow 5mm per cut, which suits a typical blade. If your blade is wider, allow a little extra.
If a step is wider than the stock length (3620mm for most ranges, 2700mm for PVC rubber and 2400mm for industrial metal), you’ll need two pieces joined together on that step. The calculator counts the extra length for you. For a seamless finish on very wide stairs, ask us about your options.
All calculator prices are ex GST and exclude delivery. GST and freight are added at checkout or in your quote. Full lengths are oversize, so their delivery includes an oversize and manual handling fee.
For stairs that need AS1428.1 compliance, choose a 10mm profile with a 50–75mm strip, such as aluminium RCF10 or RCF10BLK, recessed RNR10, fibreglass FG10 or FG50 strips, or industrial RMN1050 or RMN1075. Pick a colour with at least 30% luminance contrast to your tread. Requirements vary by building class, so confirm with your building certifier or access consultant.
No. AS1428.1 and the building code ask for at least 30% luminance contrast between the nosing strip and the tread.
If a landing edge forms the top or bottom of a step, it needs the same grip and contrast as the treads, so add it to the calculator as a step. Check landing requirements for your building with your certifier.
Stock lengths go out same day on most orders placed before 12pm. Cut-to-size orders take a little longer to dispatch because each piece is cut and the insert fitted. Big project? Send us your stair schedule for a quote, usually within 1 business day.
Yes. Our free stair nosing sample pack lets you check profiles and insert colours against your own treads before you buy.
