Building Products Distribution Racking: L&W Supply

Drywall, insulation, ceiling grid and steel studs are stored by three completely different rules — and one of them is not a rack problem at all.

The project

L&W Supply is a distributor of interior building products. Material Handling USA supplied cantilever rack and pallet rack in 2022 and again in 2023. The client, those years and the product categories supplied are the only project details we publish.

Interior building products deserve separate treatment from a lumber yard or a general construction supply yard, because the flagship product — gypsum board — behaves unlike anything else in distribution. It is heavy, fragile at the edges, damaged by moisture, and shipped in stacks that are handled by boom truck rather than by pallet jack. This page covers how we approach pallet rack systems and cantilever storage for a building products branch: what goes on rack, what stays on the floor, and where the damage costs come from.

Three load shapes, three systems

Nearly everything in an interior products branch falls into one of three shapes, and each has one correct storage answer.

Sheet and board goods — gypsum board, cement board, sheathing, hardboard. Stored flat in stacks, mostly at or near floor level, moved with a boom truck or a sheet handler. Racking these overhead is the exception, not the rule.

Long stock — steel studs and track, ceiling grid, corner bead, trim, joint tape rolls and lath. Ten to sixteen feet long, light per piece but heavy per bundle. This is cantilever territory.

Boxed, bagged and palletized goods — joint compound, fasteners, insulation bags, adhesives, tools and accessories. Conventional pallet rack and shelving.

The failure mode in this sector is treating all three as one storage problem and buying a building full of identical selective bays. Half the inventory then lives on the floor because nothing fits, and the aisles disappear.

Damage is the real cost line

In building products the storage system is judged on damaged product, not on cube. Chipped board edges, crushed grid, bent track and wet insulation are pure loss, and they come overwhelmingly from handling and from storing an item in a system that was never shaped for it.

Board and sheet goods: mostly a floor problem

Gypsum board is the product that most often gets stored wrongly, usually by someone trying to put it on rack because rack is what the building has.

Requirement Why Design response
Flat, fully supported stacks Board sags and cracks when supported at intervals rather than continuously Store flat on a level, dry floor or on full-width supports — never spanning open beams
Dry storage Gypsum core and paper facing are damaged permanently by moisture and by ground contact Keep stacks off slab contact where the floor sweats, well inside the drip line, and away from doors where wind-driven rain reaches
Edge protection Damaged edges make a sheet unsaleable even when the board is otherwise perfect Wide, clear handling lanes and dedicated sheet-handling equipment; keep forks and pallet corners away from stack edges
Access by product and length Multiple thicknesses, types and lengths look nearly identical from ten feet away One stack position per product and length, marked clearly on the floor as a location, not just as a paint line
Load reach Board is loaded to trucks by boom or by sheet handler, not by pallet jack Design lane widths and stack orientation around the loading equipment, and keep the boom approach clear

Where board does go on structure, it is on purpose-built decked bays sized for the full sheet with continuous support, not on standard beams. Otherwise the correct answer is a well-marked, well-drained floor plan with the rack built around it — which is exactly why a building products branch cannot be laid out with a rack drawing alone.

Long stock on cantilever racking

Studs, track, grid, bead and trim are what cantilever racking exists for. With no front columns, a bundle can be placed or drawn from the side without fighting an upright, and arm spacing can be set for the bundle rather than for a pallet.

Specification points that matter in this sector:

  • Medium duty is usually right. Studs and grid are long but light per foot; heavy-duty structural cantilever is often over-specified here. Match the arm and column to the real bundle weight and let the savings buy more arm levels.
  • Arm length must exceed the bundle depth. Overhang beyond the manufacturer’s allowance is where cantilever failures begin.
  • Closer arm spacing for flexible material. Long, light bundles sag between arms. Grid and trim need more support points than lumber of the same length.
  • Lipped or inclined arms for loose lengths. Loose pieces roll; banded bundles do not. Specify to how the product actually arrives.
  • Column height is set by the aisle, not the ceiling. A tall single-sided run against a wall needs anchoring and bracing designed for the overturning moment, and a truck that can reach the top arm safely.

Our lumber yard racking case study covers the heavy-timber version of the same problem, and the construction supply yard case study covers bagged goods and will-call counters.

Pallet rack for boxed, bagged and palletized goods

The pallet rack half of a building products branch looks conventional but carries two specific demands: heavy compound pallets, and fast selective access for will-call and truck loading.

Selective rack, deckedSelective pallet racking with wire decking handles bagged insulation, compound, adhesives and accessories. Decking matters because so much of this product arrives on marginal pallets or in loose bundles.
Heavier frames at the low levelsJoint compound and fasteners are dense; the bottom two levels of a building products run routinely carry more than the rest of the building. Specify from the heaviest real pallet, not the average.
Structural rack where trucks work hardStructural pallet rack is worth the premium in the will-call and dock bays where lift trucks work fast in tight quarters and contact is routine.
A pick face for accessory itemsSmall accessories picked by the piece do not belong in pallet positions. A shelving or bin pick face beside the counter keeps them out of the rack and out of the aisle.

Yard, dock and boom truck loading

Building products branches load differently from almost any other distributor: much of the outbound volume goes onto boom trucks and flatbeds rather than through a dock door, and a good share of it is delivered to a jobsite the same day.

  • Design the loading lane first. A boom truck needs a straight approach, overhead clearance and room to swing. Rack that blocks that approach costs more in loading time than it saves in storage.
  • Keep same-day product nearest the loading lane. The branch’s throughput is set by how fast a truck can be built, not by how much is stored.
  • Protect outdoor steel properly. Yard cantilever needs a galvanised or otherwise protected finish, base details that tolerate standing water and freeze–thaw, and drainage that does not undercut the footings.
  • Separate people from the loading area. Contractor foot traffic in a branch that is also loading boom trucks is a serious hazard; mark and physically separate the will-call route.
  • Plan for the returns flow. Unused jobsite material comes back damaged, mixed and unlabelled. A defined receiving and inspection position stops it becoming a permanent pile.

Capacity, protection and inspection

Beam and frame ratings are not one number. Beam capacity is published for a uniformly distributed load; a dense compound pallet or a banded bundle set down at mid-span is not that. Frame capacity depends on the number of levels and their spacing, so moving a beam changes the rating. Ask for the manufacturer’s load table for the exact span and spacing you are buying, and keep the load application drawing — pallet racking weight capacity and pallet rack uprights cover the detail.

Anchor everything, and protect what gets hit. Anchors are part of the engineered design. Aisle ends, door-side runs and cantilever base plates take the impacts; column protectors and rack guards are far cheaper than frame replacement and the downtime around it.

Inspect on a schedule and after every impact. A struck upright or a bent cantilever arm reduces capacity until it is repaired — see rack repair and inspection. In a branch where forks pass within inches of steel all day, this is not an annual formality.

Install to the drawing. Plumb, square, anchored and braced as designed; that is what every rating assumes. Our installation teams handle the engineering-relevant details as well as the steel.

Relevant references: ANSI MH16.1 for industrial steel storage racks and OSHA 1910.176 on securing stored material against collapse. Neither replaces a stamped design for your building, your seismic category and your loads.

Building products racking FAQs

Can drywall be stored on pallet racking?
Only on purpose-built bays that support the full sheet continuously and are designed for the stack weight. Board spanning standard open beams sags and cracks. In most branches gypsum board is stored flat in marked floor positions and the rack is built around it.
What is the best racking for steel studs and ceiling grid?
Medium-duty cantilever racking with arm spacing close enough that long, light bundles do not sag, arms longer than the bundle depth, and one column position per product and length. Heavy-duty structural cantilever is usually over-specified for this material.
How is a building products branch different from a lumber yard?
Lumber is heavy per foot and tolerant of weather; interior products are lighter, far more easily damaged and often ruined by moisture. That pushes interior products indoors, onto medium-duty cantilever, and makes handling damage rather than cube the main design driver.
Does outdoor cantilever racking need a special finish?
Yes. Outdoor runs need galvanised or otherwise protected steel, base details that tolerate standing water and freeze–thaw cycling, and drainage that keeps water away from the footings. Painted indoor rack put outside will corrode at the base first.
How much aisle width does a building products branch need?
It follows the equipment and the product length, not a rule of thumb. Sheet handlers, boom trucks and sixteen-foot bundles all need room to turn and swing. Size the lanes around your real loading method before finalising the rack layout.
What is the fastest improvement in an existing branch?
Usually separating the three load shapes properly: getting long stock off the floor and onto cantilever, giving board dedicated marked floor positions, and freeing the pallet rack for what it is good at. That alone recovers aisle space and cuts damage.
