Storage mezzanines
Floors for shelving, cartons or light pallets, with pallet gates and loading points.
Project types · Mezzanines & equipment platforms
Double your floor area without a new building
Office and storage mezzanines, e-commerce picking levels, plant and equipment platforms inside existing warehouses and factories. Designed for your loads, fabricated in our own factory and shipped as bolt-together kits.

Using the height you already have
The cheapest square metre is the one above your head
Many Thai warehouses and factories have 8–12 m of clear height but use only the floor. A steel mezzanine turns that air into offices, storage, picking floors or a platform for machines, at a fraction of the cost and time of a new building, and without a new building permit in many cases (your Thai engineer confirms).
We design each mezzanine for its real loads, from office use to pallet racking and heavy equipment, check the existing slab and columns with your engineer, and fabricate a bolted kit with stairs, handrails and pallet gates in our factory. Installation is planned around your operations, often in zones over weekends.
- Offices, storage, picking and equipment platforms
- Free-standing or tied into the existing frame
- Stairs, handrails, pallet gates and decking included
- Bolted kits installed zone by zone
Structural solutions
What we build above the floor
Each option is engineered member by member in our design office, then built on our own fabrication lines.
E-commerce picking levels
Multi-tier picking floors with conveyor openings and chutes.
Office mezzanines
Offices, meeting rooms and QC labs above production or storage.
Equipment and plant platforms
Platforms for chillers, compressors, tanks and process machines, with access stairs.
Maintenance walkways
Catwalks, crossovers and access ladders along lines and conveyors.
Fire-rated mezzanines
Intumescent protection where escape routes or Thai rules require fire-rated floors.
Your challenges, our answers
What owners ask us, and how we solve it
The questions we hear most often from Thai owners, designers and contractors.
Challenge 01
Will the existing slab carry it?
Our answer
We provide column loads early so your engineer can check the slab; base plates are sized to spread the load.
Challenge 02
No shutdown allowed
Our answer
Bolted kits are installed in zones, often outside working hours.
Challenge 03
Columns in the way of racking
Our answer
Column grid set around your racking, aisles and forklift routes.
Challenge 04
Floor vibration
Our answer
Beams sized for stiffness so office floors and picking levels feel solid.
Challenge 05
Safety on upper floors
Our answer
Handrails, toe boards, pallet gates and stairs are part of the kit.
Challenge 06
Changing needs later
Our answer
Bolted design lets a mezzanine be extended or relocated.
Inside the structure
Typical design ranges for mezzanines and platforms
Every project is engineered to its own brief and site. These are the ranges we work in most often.
| Design item | Typical range we engineer |
|---|---|
| Floor load | Office, storage or equipment loads as specified |
| Column grid | About 4–8 m, set around racking and aisles |
| Deck | Steel deck with board, composite deck or grating |
| Height | Single or multi-tier within the existing building |
| Access | Stairs, ladders, pallet gates and goods lifts |
| Fire protection | Intumescent paint where fire-rated floors are required |
| Connection | Free-standing or tied to the existing frame after checks |

FAQ
Questions Thai clients ask us
Do I need a building permit for a mezzanine?
It depends on the size and use and on the local authority. Your Thai engineer confirms; we provide drawings and calculations if a permit is needed.
Can the existing slab carry the mezzanine?
We give you column loads early so your engineer can check the slab. Larger base plates or local footings can be added if needed.
How long does installation take?
A typical mezzanine kit is installed in days to a few weeks, zone by zone, so operations can continue.
Can a mezzanine carry pallet racking?
Yes, if designed for it. Tell us the rack and pallet loads and we size the floor and columns accordingly.
Can it be moved or extended later?
Yes. Bolted connections allow a mezzanine to be extended, reconfigured or relocated.
