Frequently Asked Questions

A light-duty steel mezzanine for storage and light equipment loads runs $18,000 – $35,000. A heavy industrial mezzanine sized for equipment loads, forklift traffic, or a process floor runs $35,000 – $75,000 and up. Those are 2026 Northern California budget ranges for the structure only, fabrication rather than installation. What moves the number is the load case, the column grid you can live with, the deck type, and the stair and guardrail scope.

Mezzanines

A standard 2-line steel handrail runs $140 – $185 per linear foot to fabricate. A 42-inch OSHA guardrail system runs $165 – $225 per linear foot. An ADA compliant rail, which needs a continuous graspable profile plus code-compliant returns and extensions, runs $180 – $240 per linear foot. Decorative banisters run $200 – $300. Fabrication only, installation quoted after a site visit.

Handrails and guardrails

A steel fixed ladder in the 20–30 foot range costs $3,500 – $7,500 to fabricate. A steel-framed roof access hatch to pair with it runs $3,500 – $8,000. The variables are height, whether a cage, well, or ladder safety system is required, the landing and platform configuration, and the finish.

Ladders and access hatches

A single-dumpster enclosure runs $4,500 – $7,500. A double-dumpster enclosure runs $7,500 – $14,000. Mechanical and generator enclosures run $8,000 – $25,000 and up depending on the equipment being screened and the clearances it needs. Most municipalities publish a required detail that dictates dimensions, gate swing, and bollard placement, so the local standard often drives more of the price than the finish does.

Enclosures

Standard steel pipe bollards cost $450 – $850 each to fabricate. Decorative and architectural bollards run $950 – $2,500 each. Removable or locking bollards, used for fire lanes and controlled access, run $1,500 – $3,500 each. Installation is quoted after a site visit because the cost is driven almost entirely by what is under the slab. Core drilling into an existing slab with unknown utilities costs meaningfully more than setting bollards in new construction.

Bollards

A residential sliding gate runs $12,000 – $25,000. A commercial gate runs $25,000 – $60,000 and up. A heavy industrial gate starts at $60,000. Automation hardware is excluded unless specified, so operators, loop detectors, safety edges, and access control are a separate line. Span, wind load, whether it slides or swings, and the finish are the main drivers.

Gates

A residential balcony structure runs $12,000 – $25,000. A commercial deck frame runs $25,000 – $75,000 and up. Both are steel structure only. Decking, waterproofing, railing, and finishes are separate scopes, and railing typically adds $140 – $240 per linear foot depending on whether it is standard, OSHA guardrail, or ADA-compliant.

Decks and balconies

Laser-cut decorative panels run $55 – $95 per square foot. Privacy screens run $75 – $120 per square foot. Pattern density is the main driver, because more cutting means more machine time and a weaker panel that may need a heavier gauge or a frame. Material and finish are the other two variables.

Decorative panels

Fabrication-only pricing covers engineering, materials, shop labor, and the finish on the steel itself. It does not include installation, site preparation, concrete or footings, electrical or automation hardware, permits and plan-check fees, crane or rigging time, decking or infill materials, or freight beyond the standard delivery area. Installation is quoted after a site visit and field review because the site drives that number far more than the part does.

2026 price guide

Start from the published ranges, then add the scopes fabrication pricing excludes. Worked example: a 1,000 square foot light-duty mezzanine with 60 linear feet of 42-inch OSHA guardrail budgets at roughly $18,000 – $35,000 for the structure plus $9,900 – $13,500 for the guardrail, which is 60 feet at $165 – $225. That is $27,900 – $48,500 fabricated. Then add installation, footings or slab work, permits and plan check, deck material, and any fire protection.

2026 price guide

Because almost every fabrication job is genuinely custom, and publishing a number invites a comparison the shop cannot control. The tradeoff is that a facility engineer trying to build a capital request has to collect three quotes before learning whether the project is a $20,000 problem or a $70,000 one. We publish the ranges for that reason. They are wide on purpose, they cover fabrication only, and they are meant for scoping rather than contracting.

2026 price guide

A modular mezzanine is a catalog kit sized from a standard grid, usually sold by a racking or material-handling dealer, and it is the right answer for straightforward storage in a clear-span building. A custom mezzanine is engineered to the actual load case, the actual column locations, and the actual obstructions, and it is the right answer when equipment goes on top, when there is existing structure to work around, or when the deck carries a process. The price ranges overlap, since light-duty custom structures run $18,000 – $35,000, so the decision is usually driven by fit rather than cost.

Mezzanines

Separating them is standard practice and it creates a predictable failure: the engineer produces a design that is technically correct and awkward to fabricate, the shop builds exactly what is drawn even when it will not work in the field, and nobody owns the gap. One firm with engineers and fabricators in the same building removes it, because the person drawing the connection knows what the shop can cut and what a crew can erect. The tradeoff is a smaller bidder pool.

All services

It depends on how much of the job is steel and equipment versus building work. A general contractor is right when the project is largely construction: new structure, concrete, envelope, multiple trades. A fabrication shop with field crews is right when the project is largely equipment and support steel, because design, fabrication, and installation stay inside one company. The failure mode to avoid is a general contractor treating a modest equipment install as filler work between larger jobs.

Equipment installation

Hot-dip galvanizing, powder coat, shop primer with field paint, and specialty coatings. Finish type is one of the largest single cost variables on a steel package, and it also adds a cycle outside our building. Tell us the environment, indoor or outdoor, washdown, coastal, or corrosive, and we will recommend rather than default to whichever is cheapest.

Steel fabrication

It means the structure is designed to be cleaned, not merely to be strong. In practice: continuous welds rather than skip welds, ground and polished seams, sloped surfaces that drain instead of pooling, no horizontal ledges that collect product, material selection that survives caustic and high-pressure washdown, and connection details that can actually be reached with a cleaning tool. It costs more to fabricate, and it is the difference between passing an inspection and rebuilding the platform in eighteen months.

Food processing · Custom equipment

An enclosure engineered to a specific hazardous-area classification, where the construction, ventilation, and pressure-relief design are dictated by the classification rather than chosen. In plants handling combustible dust, flammable vapors, or reactive chemicals, the enclosure's job is to contain a defined event and direct relief safely. These are not catalog products. The classification, relief requirement, and the equipment being enclosed determine the design.

Specialized enclosures

Yes. Installing already-purchased structures and equipment for the end user is a defined service line within 600 miles of Sacramento. If a supplier shipped you a mezzanine kit or a rail package and you need somebody competent to erect it, that is a normal job. Note that you may still need a local engineer to stamp the anchorage into your slab.

Steel fabrication

Field services, equipment setting, and rigging reach 600 miles from Sacramento, which covers essentially all of California and reaches across the West. Full EPC delivery and scheduled preventative-maintenance programs reach 300 miles, covering Northern California, the Central Valley, the Bay Area, and Reno-Tahoe. Engineering, design, drafting, fabrication, and shipping are nationwide. The shop is at 2530 Mercantile Dr, Ste H, Rancho Cordova, California.

Service area

By road, roughly: all of California, with Fresno at about 171 miles, Los Angeles at about 384, and San Diego at about 504. Nevada, with Reno at about 132 miles and Las Vegas at about 570. Oregon, with Medford at about 308, Eugene at about 474, and Portland at about 580. Idaho, with Boise at about 551. Outside the radius by road: Salt Lake City at about 652 miles, Seattle at about 752, and Phoenix at about 755. Those are approximate driving distances, not straight-line.

Service area

Not on a California licence alone. Nevada requires its own licence under NRS Chapter 624, though the State Contractors Board offers licensure by endorsement that can waive the trade exam for a contractor holding an active, unrestricted California licence for four or more years. Oregon requires a Construction Contractors Board licence with no California reciprocity, and ORS 701.021 covers soliciting as well as performing work. Idaho requires registration for private work and a separate public-works licence. Design, engineering, fabrication, and shipping do not implicate a contractor licence in any of those states. We verify licensing per state before mobilizing.

Service area

Mobilization is quoted as a visible line item rather than buried in unit pricing, and on larger projects it is often folded in. At distance, work gets planned around it: field-verify first, fabricate everything in the shop against real measurements, and arrive with the assemblies, the fasteners, and the spares, because a missing bolt 170 miles out is a six-hour problem instead of a twenty-minute one.

Service area

Because they are different commitments. An install is a single mobilization with a defined window. A maintenance subscription means being at your facility on a schedule, repeatedly, for years, and an EPC project means months of active project management with the ability to respond quickly when something changes. Those two services are held at 300 miles because that is the distance at which the commitment can actually be kept.

Preventative maintenance

Scheduled preventative maintenance visits, replacement of filters, belts, and agreed-upon consumable components, equipment lubrication and minor adjustments, verification of safety devices and interlocks, and facility condition assessment and reporting with photographic documentation of deficiencies or concerns. Program tiers are recommended based on the needs of the facility.
