What to look for when comparing mezzanine stair quotes

You’ve got a few quotes for mezzanine stairs. The prices are different, the descriptions don’t quite match up, and it’s hard to tell what you’re actually comparing. Before you go with the cheapest number on the page, here’s what’s worth paying attention to.

Check what’s actually included

This is the biggest reason quotes look different. They’re often not quoting the same scope.

Some quotes cover stairs only. Others include stairs, handrails, balustrade, fixings, nosings, and tactile indicators as a complete package. If one quote is $4K cheaper but doesn’t include handrails or balustrade, it’s not cheaper. You’re just going to pay for those separately and coordinate another supplier on top.

Before you compare prices, ask every supplier to spell out exactly what’s in the quote and what’s not. A line item breakdown is worth more than a lump sum number.

Things that should be clearly listed:

Stair stringers and treads
Handrails
Balustrade panels
Fixings, bolts, and brackets
Nosings
Tactile indicators (if required)
Freight

Ask about the finish

If any of those are missing from a quote, they haven’t disappeared. They’ve just become your problem to sort out later.

A quote might say “steel staircase” without telling you what finish you’re getting. That matters more than it sounds.

There’s a meaningful difference between raw primer, galvanised, and powder coated finishes. A lot of custom-fabricated stairs arrive on site in raw primer. That means you need to organise a painter, wait for it to dry, and hope nothing gets scratched or chipped during the rest of the install. That’s time and cost that doesn’t show up on the original quote.

Pre-finished stairs (powder coated or galvanised) arrive ready to install. No painting, no drying time, no touch-ups. The finish is done before the stairs leave the factory.

When you’re comparing quotes, check whether the price includes a finished product or a product that still needs work on site before it’s ready for handover.

Understand the install method

Not all mezzanine stairs go in the same way, and the install method changes what you need to have organised on site.

Welded/fabricated stairs are typically built as a single unit off site and delivered whole. Installing them usually requires a crane to lift the staircase into position, a boilermaker on site to weld it in, and grinding and painting to clean up the welds after. That’s a full day minimum, sometimes two, plus the cost of a crane hire and a qualified welder.

Modular bolt-together stairs arrive as a kit of pre-cut, pre-drilled components that get assembled on site. Two people can typically install a full stair, handrail, and balustrade package in a few hours with hand tools. No crane, no welding, no hot work permits.

Neither approach is wrong. But they have very different site requirements, timelines, and costs that don’t always show up in the stair quote itself. It’s worth asking the question so you know what you’re signing up for on install day.

Look at the lead time, not just the price

A quote that’s 10% cheaper doesn’t save you anything if it takes six weeks longer and pushes your handover date.

Lead times for custom-fabricated stairs can range from four to eight weeks depending on the fabricator’s workload. Modular systems with standard configurations can often be turned around much faster because the components are manufactured to set specs rather than built from scratch each time.

When you’re comparing quotes, ask for a specific lead time in writing. And ask what happens if your measurements or specs need to change after you’ve ordered. Some suppliers can adjust mid-production. Others need to start again, which resets the clock.

If you’re working to a tight program, the lead time might matter more than the price.

Check the compliance documentation

Your mezzanine stairs need to meet AS1657. If accessibility is a requirement, they also need to meet AS1428. That’s not optional, and your building inspector will be checking.

The question is whether compliance is engineered into the product before it arrives on site, with documentation ready to hand to your inspector, or whether it’s left to the installer to figure out and verify during the build.

Pre-engineered systems come with compliance documentation from the manufacturer. The specs, load ratings, and dimensional requirements have been confirmed before the product leaves the factory. That means less back and forth during inspections and less risk of something getting flagged after install.

When you’re comparing quotes, ask each supplier what documentation comes with the delivery and whether their product has been engineered to the relevant Australian Standards.

Ask about delivery and packaging

This one gets overlooked until install day, and by then it’s too late.

A few questions worth asking:

Is freight included in the quote, or is it added on top?
Are components packed and protected for transport, or do they arrive loose?
Are all the fixings, bolts, and brackets included, or do you need to source them separately?
Does the delivery include an installation guide or assembly instructions?

Think about what happens next time

If you’re building one mezzanine on one site, this section matters less. But if you’re a builder or developer working across multiple projects, it’s worth thinking about now.

Can the supplier keep your spec on file so you don’t have to re-quote from scratch every time? Can they deliver the same configuration consistently across different sites? If you’re building 10 or 20 units on the same development, are the stairs going to look and fit the same in every one?

Standardising your stair spec across projects removes a variable you don’t need to manage. It means faster ordering, predictable lead times, and a consistent result that doesn’t require re-thinking for every new build.

If repeat work is likely, it’s worth raising this early and finding out whether the supplier is set up to handle it.

The bottom line

The cheapest quote isn’t always the cheapest job. Once you factor in the finish, the install method, the lead time, what’s actually included, and the compliance documentation, the numbers usually tell a different story.

It’s not about finding the most expensive option either. It’s about understanding what you’re actually getting so you can make a fair comparison.
