Dmytro and Lenokers went above and beyond my expectations. We were looking to liquidate a good amount of pallet racking from our warehouse and between our first contact and our warehouse being cleared of our racking, barely a week had passed! They were kind, courteous, and more than professional for the entire experience. I would not hesitate working with them again!

We had to move some inventory around very quickly to make room for a new customer and we ran out of rack space. I called Lenokers and they had exactly what we needed. Within 3 hours we had our racking and we're back to getting organized!
Thanks guys!
Kristin Bowen
It was a pleasure working with Dmytro and his team to improve our warehouse! Timely communications and service.

How is a steel mezzanine priced?
By area, deck load, column spacing, decking, stairs and gates, plus engineering, permits, freight and installation. Send the area, the height and what the deck is for, and we price the design. See warehouse layout design.
How much weight can a steel mezzanine hold?
Storage and work decks are commonly designed for 125 to 150 pounds per square foot; heavier uses are designed for their real loads. The rating is set in the engineered drawings.
Do I need a permit for a mezzanine?
In most places, yes. We prepare the stamped drawings, check the area limit and the stairs against the building code, and help through the permit. See permits and code compliance.
How long does a mezzanine take?
Drawings and permit usually take the longest. Once approved, a bolted mezzanine goes up in days, not months, depending on its size.
Can I put an office on a mezzanine?
Yes. Office use is designed into the deck and the stairs; the walls, power and fire protection are planned with it.
Is a modular mezzanine as strong as a built one?
A bolted steel mezzanine is engineered for its load like any structure. Modular means it is made in sections and bolted on site, so it can be extended or moved later.

About steel mezzanines
A steel mezzanine is a free-standing floor built inside your building: columns, beams and joists bolted together, with a deck on top and stairs and guardrails around it. It adds space for storage, packing, offices or production without moving or expanding. Medium-duty, commercial-grade mezzanines are typically designed for 125 to 150 pounds per square foot. Lenokers designs, permits and installs steel mezzanines, shipped from points across the US, supply only or installed by our own crews.
Stairs, gates and guardrails
Every mezzanine needs a safe way up and a safe edge: steel stairs with handrails, a 42″ guardrail with a midrail and toeboard on every open edge, and a pallet gate where goods are lifted onto the deck.
Decking choices
Resin board on steel deck gives a smooth, quiet floor for carts and offices; bar grating lets light and sprinkler water through and suits storage; plywood on steel deck costs least.
Columns, spans and the space below
Columns stand where the layout allows; longer spans need deeper beams. We plan the column grid around the aisles and work areas you keep under the deck.
Permits and the building code
The area allowed, the stairs, the guardrails and the deck rating are checked in stamped drawings. We prepare them and help through the permit, then build to them.
