We design and install mezzanine racking systems that do two things at once: carry a working floor above, and support pallet storage below. It's not a mezzanine built over existing racks — it's a single integrated structure, PE-stamped as one system, designed to your actual loads, forklift clearances, and warehouse dimensions. We've been fabricating these in Singapore since 2014, and we handle the full scope: survey, engineering drawings, BCA submission if required, fabrication, and installation. This is one of the most space-efficient ways to double your usable area when your lease won't let you move and your slab won't let you stack higher.

What Is Mezzanine Racking and How Does It Work?

A mezzanine racking system is a structural steel platform supported by racking uprights that are engineered to carry both the floor load above and the pallet loads below. The uprights do double duty: they act as mezzanine columns and as pallet rack frames. The beams below carry pallets. The beams at mezzanine level carry the floor joists or decking. Above that, you get a full working floor — typically used for picking, light assembly, carton storage, or office space.

Every mezzanine racking system we install is designed by a Professional Engineer and stamped with their PE seal. The design accounts for:

• Pallet load per level — we calculate this based on your actual SKU weight, pallet dimensions, and beam span
• Mezzanine live load — minimum 5 kN/m² for light use, higher if you're storing cartons or operating equipment on the upper floor
• Forklift aisle width and turning radius — so your fleet can actually access the lower-level pallets without damage
• Slab capacity — because the point loads from the uprights must be within the existing floor slab's rated capacity
• Fire egress and BCA compliance — staircase width, handrail height, fire-rated access if the mezzanine area and use class trigger a submission

If the mezzanine floor area exceeds a certain threshold or if it's used for a controlled activity, BCA submission is required. We coordinate this as part of the project. We've done this for 3PL operators in Tuas, electronics warehouses in Woodlands, and food distribution centres across the island.

Why Combine a Mezzanine with Racking Instead of Building Separately?

Because it's cheaper, faster, and structurally more efficient. A standalone mezzanine uses heavy columns that take up floor space and contribute nothing to your storage capacity. A mezzanine racking system uses the rack uprights as columns — so the same steel does two jobs. You store pallets below, and you gain a full floor above, without losing aisle width or pallet positions.

We've also seen operators try to retrofit a mezzanine over existing racks. It rarely works. The original racks were not designed to carry a floor load. The uprights weren't sized for it. The beam spacing is wrong. The anchoring is inadequate. You end up ripping it out and starting over, which costs more than doing it right the first time.

When we design a mezzanine racking system, we size everything from the start: upright gauge, beam depth, floor joist spacing, and anchorage — all calculated as one integrated structure. It's not a mezzanine sitting on racks. It's a single system that happens to do both jobs.

What Can You Store or Do on a Mezzanine Racking Floor?

It depends on the live load rating we engineer into the design. Most of our mezzanine racking floors are rated for one of three use cases:

• Picking and light carton storage — 5 kN/m² live load, timber or steel decking, manual access only
• Heavy carton storage or light equipment — 7.5 to 10 kN/m² live load, steel decking, pallet truck access allowed
• Office or showroom space — 3 to 5 kN/m² live load, timber or composite decking, finished floor, partitioned if needed

We've installed mezzanine racking systems where the lower level carries 1,000 kg pallets on selective beams, and the upper floor is used for order picking with roller conveyors. We've done others where the top floor is a full air-conditioned office with meeting rooms and the ground level is drive-in racking for FMCG pallets. The flexibility is real, but only if the engineering is done up front.

What you cannot do: use the mezzanine floor for anything heavier than the PE-stamped design load. If your drawing says 5 kN/m² and you start stacking 200 kg cartons three high, you've exceeded the rating. We've been called in to reinforce systems where operators did exactly this, and it's always more expensive than getting the load rating right at the start.

When Is BCA Submission Required for a Mezzanine Racking System?

BCA submission depends on the total mezzanine floor area and the use class. If the mezzanine is used for storage and exceeds a certain size, or if it's used as an occupied space like an office, submission is typically required. The exact threshold varies depending on the building's existing Temporary Occupation Permit (TOP) status and the intended use of the mezzanine floor.

We handle BCA submissions as part of our mezzanine racking projects. This includes:

• Engaging the Professional Engineer to produce stamped structural drawings
• Preparing architectural plans showing staircase, handrails, and fire egress
• Coordinating M&E drawings if you're adding lighting, power, or ACMV to the upper floor
• Submitting to BCA and attending to any comments or resubmissions
• Arranging for the final PE inspection and sign-off after installation

If your mezzanine doesn't require BCA submission, we still produce PE-stamped drawings and a Supervision Certificate. This is your proof that the structure was designed and installed to Singapore structural codes, and it's critical if you ever need to make an insurance claim or satisfy a landlord's due diligence during lease renewal.

How We Design and Install a Mezzanine Racking System

Every mezzanine racking project starts with a site visit. We measure the warehouse, check the slab condition, confirm ceiling height and obstructions, and map out your forklift fleet and turning radius. We also ask about your future plans — are you growing your SKU count, changing your pallet sizes, adding more forklifts? Because once the mezzanine is in, changes are expensive.

From there, we produce a layout drawing showing:

• Upright positions and spacing
• Beam levels for the lower racking
• Mezzanine floor level and joist layout
• Staircase location, width, and handrail details
• Aisle widths and forklift access zones

Once you approve the layout, we engage a PE to produce the structural calculations and stamped drawings. We fabricate the uprights, beams, floor joists, and decking in-house — cold-roll formed steel with beam end-plates welded and powder-coated. Heavy sections are imported where required. All materials come with mill certificates.

Installation takes between one and four weeks depending on the system size. We work in stages: install the uprights, secure the lower beams, erect the mezzanine beams and joists, lay the decking, install the staircase and handrails, then test and inspect. If BCA submission is required, the PE inspects the completed structure and issues the Supervision Certificate.

What Does a Mezzanine Racking System Cost in Singapore?

We don't publish fixed prices because every system is custom-designed. Cost depends on:

• Mezzanine floor area — larger floors require more joists, more decking, and heavier uprights
• Live load rating — a 10 kN/m² floor costs more than a 5 kN/m² floor because it needs deeper joists and heavier beams
• Lower-level racking configuration — selective, double-deep, or drive-in below the mezzanine
• Staircase and access — single staircase or multiple, with or without goods lift access
• BCA submission and PE fees — if submission is required, add PE design, submission coordination, and inspection

As a guide, most of our mezzanine racking systems fall between $40,000 and $150,000 depending on scope. We provide a fixed-price quotation after the site survey and layout approval, and we don't charge extra for design revisions or minor layout tweaks. If you need BCA submission, we quote that separately so you know exactly what you're paying for.

Common Mistakes We Fix When Clients Come to Us

We've spent two decades fixing other people's mezzanine racking mistakes. Here are the four we see most often:

• Racks not designed to carry a floor load — someone bolted a mezzanine on top of standard selective racks, and the uprights are buckling. We have to strip it down and re-engineer the entire system.
• Forklift can't access the lower pallets — the mezzanine floor was built too low, or the upright spacing doesn't match the forklift turning radius. Result: wasted pallet positions or daily damage.
• No BCA submission when required — operator built a 200 m² mezzanine without submission, landlord found out during lease renewal, now they need to regularise or tear it down.
• Floor decking not rated for the actual load — operator stacked cartons three high on a 5 kN/m² floor, decking is sagging, and the PE won't sign off on an inspection.

Every one of these is avoidable if you do the design work up front, with accurate information and honest advice. That's what we do.

Frequently Asked Questions

Can I add a mezzanine to my existing selective racking?

Not unless the existing racks were originally designed to carry a floor load, which they almost never are. Standard selective racks are rated for pallet loads only. Adding a mezzanine floor on top overloads the uprights and voids any PE certification. We've seen this attempted, and it always ends with a full re-engineering or removal. If you want a mezzanine racking system, we design it as one integrated structure from the start, with uprights and beams sized to carry both the pallets below and the floor above.

Do I need BCA approval for a mezzanine racking system?

It depends on the mezzanine floor area and use class. If the mezzanine is large or used as occupied space — like an office or showroom — BCA submission is typically required. We coordinate the submission as part of our mezzanine racking projects, including PE drawings, architectural plans, and final inspection. Even if submission isn't required, we still provide PE-stamped drawings and a Supervision Certificate, so you have full documentation for insurance and lease compliance.

How much weight can a mezzanine racking floor hold?

It depends on the live load rating we engineer into the design. Most of our mezzanine floors are rated between 5 kN/m² and 10 kN/m². A 5 kN/m² floor is suitable for picking and light carton storage. A 10 kN/m² floor can handle heavy cartons or light equipment like pallet trucks. The rating is shown on the PE-stamped drawings and must not be exceeded. If your storage needs change, we can inspect and re-engineer the floor, but it's always cheaper to get the rating right the first time.

Can I use a forklift on the upper mezzanine floor?

Only if the mezzanine floor is designed for forklift loads, which requires a much higher live load rating and a reinforced access ramp. Most of our mezzanine racking systems use the upper floor for manual picking, carton storage, or office space — not forklift traffic. If you need forklift access to the upper level, we design the floor for the actual forklift weight, wheel load, and turning radius. This increases the steel tonnage and cost, so we only recommend it if your operation genuinely requires it.

How long does it take to install a mezzanine racking system?

Installation typically takes between one and four weeks, depending on the system size and whether BCA submission is required. Simple systems with no submission can be installed faster. Larger systems or those requiring BCA approval take longer due to the submission timeline and PE inspection schedule. We provide a detailed project timeline in our quotation, and we coordinate all trades — steel erection, decking, staircase, handrails, and final inspection — so you only deal with one contractor.
