Service Overview

Steel Mezzanines That Add Square Feet Without Adding Footprint

Your operation has outgrown the floor and the building sits tight to its property line. Expanding the shell in Houston means new site work, a new slab, a new permit and months of schedule. A structural steel mezzanine takes the space overhead instead. Jimenes Construction is a self-performing steel contractor in Houston, TX with 23 years on this ground. Our own crews detail, fabricate, weld and erect the whole system.

A mezzanine is a floor built inside your floor. Columns land on base plates anchored to the existing slab, beams carry the deck, and stairs, guardrails and pallet gates make it legal to work on. We build storage mezzanines, in-plant offices, pick modules and equipment platforms for warehouse, distribution, manufacturing and retail buildings.

Design starts with the live load rating in pounds per square foot, then the code limits on area and egress. Storage decks usually run 125 psf and office areas 50 to 100 psf. If the platform serves a machine or a pipe run rather than people and pallets, start on our platforms and catwalks page. If the slab under your columns comes back thin, our concrete slab crew thickens it before the steel arrives.

Coverage

Mezzanine Types We Build

Each one carries a different load and answers to a different code section. We build all six in house.

Storage & Pallet Mezzanines

Free-standing decks rated at 125 psf and up, with pallet drop gates, kick plates and column lines set clear of your racks and drive aisles.

In-Plant Offices & Break Rooms

Elevated office space over the production floor, framed for wall, HVAC and conduit loads, with the fire and egress details worked out first.

Work Platforms & Pick Modules

Multi-level pick and pack platforms tied to conveyor, with grating deck, transfer stairs and clearances set to the material handling drawings.

Equipment & Machine Platforms

Access and support platforms for tanks, mixers, dust collectors and process skids, sized for the machine weight and its dynamic load.

Deck Systems

Bar grating, ResinDek over form deck, checker plate and composite deck with a concrete fill where noise, spill control or fire rating matter.

Stairs, Guardrails & Gates

IBC and OSHA stairs, 42-inch guards, handrails, ships ladders and safety gates fabricated with the mezzanine so it all lands together.

Our Process

Our Steel Mezzanine Process

Five steps, the same on a 400 square foot equipment platform and a 20,000 square foot pick module. Call (832) 576-3278 to start at step one.

  1. 01

    Building Survey & Load Rating

    We measure clear height, rack lines, sprinklers and lighting. We core the slab where we need to, then set the live load rating in psf with you before pricing.

  2. 02

    Engineered Drawings & Permit

    A Texas PE seals the framing, base plate and anchor design. We check IBC area, occupancy and egress limits, then pull the permit with Houston or your county.

  3. 03

    Shop Fabrication & Finish

    Columns, beams, stringers and rails are cut, fit and welded to AWS D1.1 by certified welders, then primed, painted or hot-dip galvanized for the exposure.

  4. 04

    Anchoring & Erection

    Layout from your column grid, anchors drilled and torqued, then steel set, plumbed and bolted. Deck, stairs, guards and gates follow in the same sequence.

  5. 05

    Inspection & Turnover

    Special inspection of welds and high-strength bolting, city framing and final inspection, load capacity plaque posted at the stair, punch list closed.

Engineering & Compliance

Materials, Methods & Code Compliance

People and pallets stand on this floor. The load rating, the deck, the anchors and the inspections all follow from that.

Slab & Anchorage

  • Existing slab cored for thickness and strength
  • Base plates on post-installed or cast-in anchors
  • Thickened concrete pads added where column loads demand
  • Column grid kept clear of racks and drive aisles

Steel, Deck & Finish

  • A992 wide flange beams and A500 tube columns
  • Bar grating, ResinDek and composite floor deck
  • Shop primer, epoxy or hot-dip galvanized coatings
  • Mill test reports kept on every shape we set

Code & Loads

  • IBC mezzanine area, occupancy and egress limits
  • Live load ratings from 50 to 250 psf
  • 42-inch guards and the 4-inch sphere rule
  • Sprinkler and fire protection coordination below deck

Inspection & Sign-Off

  • Shop drawings sealed by a Texas PE
  • AWS D1.1 welds by certified welders
  • Third-party inspection of welds and bolting
  • Load capacity plaque posted at the stair

Why Choose
Jimenes Construction

One Crew From Anchor to Handrail

Detailing, fabrication, anchors, steel, deck, stairs and rails are all ours. Nothing sits waiting on a second sub. Nothing gets blamed on one either.

Built Around a Running Building

We erect inside occupied warehouses and plants every month. Column lines dodge your racks, and we work nights or weekends so shipping keeps moving.

The Load Rating in Writing

Every mezzanine ships with sealed drawings and a posted capacity plaque in psf. Your safety officer and your insurer get the number they ask for.

Line-Item Mezzanine Pricing

Steel, deck, stairs, rails, gates, anchors and slab work each get a line. You can see what a 125 psf deck costs over a 100 psf deck before you sign.

How much does a steel mezzanine cost in Houston?

There is no flat square foot rate, because two decks the same size can price very differently. Six things move the number:

  • Live load rating in psf
  • Column spacing and clear height under the deck
  • Deck type, from bar grating to composite deck with concrete fill
  • Stair count, guardrail run and pallet gates
  • Slab work under the columns
  • Whether we erect during production or after hours
Every one of those gets its own line on the estimate, so you can compare a 100 psf deck against a 125 psf deck on paper. Estimates are free and written.

Do I need a permit for a mezzanine in an existing Houston building?

Yes. An added mezzanine is new floor area, so it goes through plan review and inspection like any other construction. Inside city limits that is the City of Houston. Outside city limits it is Harris County, or Fort Bend, Montgomery, Brazoria or Waller depending on your address. Plan review wants drawings sealed by a Texas PE showing framing, base plates, anchors, stairs and guards. We pull the permit and book every inspection.

How much weight can a mezzanine hold?

That is set in design and posted when we finish. Storage decks are commonly rated at 125 psf, general work areas at 100 psf, and office areas at 50 to 100 psf. Heavy machine platforms go higher, and we size the beams and columns for the equipment weight plus its dynamic load. Every job leaves with a capacity plaque at the stair and sealed drawings for your file.

Will my existing slab carry the mezzanine columns?

Often yes, but we check instead of assuming. We core the slab for thickness and read any soil or foundation data you have, because a base plate concentrates a lot of load into a small area. Thin or cracked slabs get thickened pads under each column before the steel arrives. Our own crews handle that work, so see concrete slabs and equipment pads for how we build them.

How big can a mezzanine be, and how many stairs does it need?

Code caps most mezzanines at one third of the floor area of the room below, and larger areas are allowed only under specific conditions. Egress drives the stair count, and past a certain occupant load or travel distance you need a second stair. We check area, occupancy and travel distance before we price the steel. Stair and guardrail details live on our steel stairs and railings page.

Can you build it without shutting our warehouse down?

Yes, and most of our mezzanine work happens in a live building. We lay out column lines around racks, conveyor and drive aisles, then erect in phases so only one zone is fenced at a time. Night and weekend work is normal on distribution jobs near the Ship Channel and the Grand Parkway. See steel erection for how we sequence a live site, or call (832) 576-3278 and we will walk your building.
