The first question most buyers ask us is the one we are most careful answering: "How much is a bay?" It is a fair question. It is also the question that produces the most misleading comparisons, because two quotations that both say "per bay" are very often pricing two different things.

Here is what we publish on our pallet racking page, from recent Singapore installations: V3000 selective S$380 to S$650 per bay, V5000 S$650 to S$1,000 per bay, V8000 S$900 to S$1,400 per bay. The same page says why we do not give a single flat number: the same selective bay can vary by 50 to 80 per cent depending on the load case. This article is about that gap. What sits inside it, which items you can control, and how to read two quotations side by side so you are comparing like with like.

First, what "a bay" means on a quotation

A bay is the space between two upright frames, carrying beams at one or more levels. That is the only thing the word fixes. It does not say how tall the uprights are, how long the beams are, how many beam levels there are, what each level is rated to carry, how the frame is finished or how it is fixed to the floor. Every one of those changes the price, and a per-bay figure that does not state them is only a headline.

The five things we say move the price

When we explain the published ranges, we name five variables: height, beam length, seismic class, finish and floor-fix detail. On top of those sits the one that matters most, the load class. Taking them in turn, in the order we would check them on your quotation.

1. Load class

The number in our V-series name is the rated load per beam level in kilograms. V3000 is 3,000 kg per level, V5000 is 5,000 kg, V8000 is 8,000 kg, and V10000 covers 10,000 kg and above, design-verified project by project. The published per-bay ranges climb with that number, but they meet and overlap: V3000 tops out at S$650 where V5000 starts, and V5000 reaches S$1,000 while V8000 starts at S$900. So a bay at the dear end of one class can cost what a bay at the cheap end of the next class costs, and the next class is the one built to carry more. A low figure and a high figure can be the same steel at different ratings, or different steel at the same price. Ask any quotation what each beam level is designed to, and at what beam length.

The catalogue rating is what a beam holds in ideal conditions. The real-world rating is 70 to 80 per cent of that, to allow for impact damage, off-centre loading and corrosion, and we design to the real number. If one quotation is built to the catalogue figure and another to the real one, the first will look cheaper and carry less. Our post on choosing a load class goes through how to weigh your heaviest pallet before you decide.

2. Height and beam length

Taller uprights and longer beams mean more steel in every bay. Beam length also interacts with load: a longer beam at the same rating is a different beam. The practical point for you is that these two numbers come from your pallets and your ceiling, not from the racking supplier. A beam length is set by the pallet size and overhang, and the height by your clear height measured to the lowest obstruction under the sprinklers, so measure the clear height to that point and have both numbers ready before asking anyone for a price.

3. Seismic class

Our V6000 range carries seismic bracing on tall installations, and seismic class is one of the five variables behind the published ranges. We do not publish a figure for what it adds, because it depends on the height and the configuration. What you can do is ask each supplier whether bracing is in the price or is a variation to come.

4. Finish

Our standard finish is powder-coat. Cold-rolled sections are zinc-plated before the powder-coat, and hot-rolled sections in the Super Heavy-Duty tier are shot-blasted and primed before topcoat. A galvanised finish is available for outdoor service. A finish chosen for a dry ambient warehouse is not the finish you want in a wet or outdoor setting, so say where the racking will sit before you compare.

5. Floor-fix detail

We size base plates and fixings to your actual slab capacity, not to a generic spec. A 25 MPa slab takes typical selective loads without complaint. Drive-in and VNA racking put higher point loads through the base plates, and sometimes the slab needs reinforcement or thicker base plates. This is why we check the slab before we quote, and why a quotation that never mentions your slab has either not looked at it or has left the question for later. Later is where the extra cost tends to turn up.

Where the per-bay figure stops

The per-bay ranges are indicative figures for a bay, not a price for your job. Three things sit outside them and are the usual source of a gap between a headline price and the final one:

• Anything that is not a bay. Our written quotation is itemised, so supply, fabrication, delivery, installation and any submission work each show as their own line. If a quotation gives one number for all of it, you cannot see what has been left out.
• Trucks, for VNA. VNA racking pairs with wire-guided or rail-guided trucks, and our racking page lists the truck at S$80k to S$250k each, plus a flat-floor survey to SS DM2. The racking price does not include that. A VNA conversion also adds two to three weeks for truck procurement and flat-floor verification.
• Submissions. Standard pallet racking under 9 m generally needs no BCA submission, but racking carrying a mezzanine or a walkway, or racking above the height line, goes to PE-stamped structural calculations. That work is priced after the survey. Our post on the 9 m line explains which side of it a plan is likely to fall on.

Why we will not quote a bay over WhatsApp

Our price for a bay is only as good as four facts: the heaviest pallet you actually run, the forklift you operate, the slab you stand it on and the clear height you have. Without them a figure is a guess dressed up as a quotation, and we would rather say so than hand you one. That is why we survey first. The initial site survey is free for serious enquiries, we spend up to 60 minutes on site, and nothing is deducted if the project goes ahead and nothing is charged if you choose another contractor. We ask only that you do not book it for window-shopping.

One honest limit. If the scope is under about S$5,000, the survey costs more than the job justifies. Our smallest installs are 20 to 50 pallet positions, and below that boltless shelving is usually the better answer. For those we will recommend a local shelving supplier and name a few.

How to compare two quotations in ten minutes

Put the two documents side by side and answer these in order. Any line you cannot fill in from the paper is a question for the supplier, and it is better asked before signing than after.

1. What is each beam level designed to carry, at what beam length? Is that the catalogue figure or the 70 to 80 per cent real-world figure?
2. What are the upright height and the number of beam levels? Is the same clear height assumed in both?
3. Is seismic bracing in the price?
4. What is the finish, and is it right for where the racking stands?
5. What are the floor fixings, and has the slab been checked? Ask to see what was assumed.
6. Is it itemised? Supply, fabrication, delivery, installation and submission as separate lines.
7. Where was it made? We fabricate the great majority of our racking in our Singapore workshop. Some heavy-section profiles in the V8000 tier and above are imported, with PSB-tested mill certificates traceable to source. If one supplier imports and the other fabricates locally, ask about lead time and replacement parts as well as price.
8. What are the payment terms? We bill in milestones, typically 5 to 10 per cent deposit on signing, with the balance tied to verifiable completion stages. You can stop at any point and pay only for what has been done.

If the cheaper quotation is cheaper on every line, good. If it is cheaper because one of the eight answers is missing, you have found where the difference lives. Our post on buying racking on price alone covers what that gap looks like five years on.

What to have ready before you ask for a price

• The heaviest pallet you run, weighed, not the figure on the delivery order.
• The pallet size and any overhang.
• Your clear height to the lowest obstruction, including sprinkler heads.
• The forklift type, since it decides the aisle width.
• Whether any part of the racking will carry a mezzanine deck or a walkway.
• Where it will stand: dry ambient, wet, cold or outdoor.
• The date you need it by. A 1,000-pallet selective job typically runs 4 to 6 weeks from signed quotation to handover; our post on the survey-to-handover timeline shows where those weeks go.

The short version

• Our published ranges are V3000 S$380 to S$650, V5000 S$650 to S$1,000 and V8000 S$900 to S$1,400 per bay, indicative, from recent Singapore installations.
• A bay price means nothing until it says the load class, height, beam length, seismic bracing, finish and floor fixing.
• Trucks for VNA and any submission work sit outside the per-bay figure.
• Ask for an itemised quotation and compare it line by line, not by headline.
• We quote after a site survey, not before.
