Stop shipping "air" back to your facility. In the glass fabrication business, your profit margin is eaten by two things: Edge damage during transport and empty return freight costs. If you are still using disposable wooden crates or bulky A-frames that clutter your receiving docks, you are bleeding efficiency. Our Compact L-Racks represent a shift from "packaging" to "logistics assets"—designed specifically for high-mix tempered glass and IGU distribution. |
For any logistics manager at a wholesale glass distributor, the math is painful: You ship out a truckload of Insulated Glass Units (IGUs) on 20 A-frames, but you can only fit 20 empty A-frames on the return truck. You are paying full freight for empty steel.
The L-Shape Glass Holding Rack changes this equation through its Nesting Design. Just like shopping carts in a supermarket, the asymmetric L-base allows empty racks to slide into one another.
Empty L-racks nesting to save 70% of floor space
The Impact: You can stack 7 empty L-racks in the space of 2 loaded ones. This reduces your reverse logistics costs by up to 60% and clears up valuable floor space in your staging area, allowing your forklifts to maneuver without navigating a maze of empty iron.
In glass fabrication, a microscopic chip on the edge of a tempered sheet is a ticking time bomb. It leads to spontaneous breakage at the job site or during installation. The culprit is often the degradation of protective padding on the rack.
Standard racks use glued-on rubber. Under the intense pressure of 3,000 lbs of vertical glass, coupled with the heat of a non-climate-controlled warehouse, glue fails. The rubber slides, and the glass touches the steel.
Steel-core rubber profile mechanically fixed to prevent peeling
Our Heavy duty glass rack system utilizes a Steel-Core Rubber Profile. This is not glued; it is mechanically fastened with self-tapping screws through the internal steel spine of the rubber.
Whether you are handling standard 1/4" tempered glass or heavy architectural stone slabs, structural rigidity is non-negotiable. A rack that flexes during a truck's sudden stop creates a whip effect that snaps glass.
Handling jumbo architectural glass with full seam welded structure
We use Q235 Carbon Structural Steel with Full Seam Welding (not stitch welding). The base is engineered with a specific 90-degree angle coupled with a 3-5 degree rack tilt. This geometry uses gravity to keep the sheets stable against the backboard without creating stress points that lead to bowing.
| Feature | Compact L-Rack (Grack) | Wooden Crates | Standard A-Frame |
|---|---|---|---|
| Return Logistics | Excellent: Nests 7:1 ratio. Low freight cost. | None: Disposal cost required. | Poor: Takes up 100% volume when empty. |
| Glass Protection | High: Steel-core EPDM rubber, no contact. | Variable: Nails/staples can cause scratches. | Medium: Glued rubber often fails. |
| Shop Floor Footprint | Minimal: Can be placed flush against walls. | High: Cannot stack efficiently once opened. | High: Requires access from both sides (usually). |
| Loading Efficiency | Fast: Forklift or Crane (4-point lift). | Slow: Requires manual prying and uncrating. | Medium: Forklift access often blocked by legs. |
No. Unlike competitors who use adhesive, our rubber lined glass rack profiles feature a steel core and are screwed directly into the frame. They are designed to withstand the shear force of sliding heavy loads without detaching.
Yes. The racks are equipped with 4 welded lifting eyelets (lifting pins) on the top beam. This makes them ideal for "jobsite delivery" services where glazing contractors need to hoist the entire unit via tower crane.
Our standard heavy-duty model is rated for 1.5 to 3.0 tons (approx. 3,300 - 6,600 lbs) depending on the customization. It is suitable for dense packs of 1/4" tempered glass or multiple IGU units.
Thanks to the nesting design, you can fit approximately 98 to 112 units of our standard size rack in a 40HQ container. This maximizes your import efficiency compared to non-nesting A-frames.
For indoor use, our electrostatic powder coating (RAL 5010) offers excellent rust resistance. However, for long-term outdoor storage (common in stone yards), we highly recommend our Hot-dip galvanized option, which provides 10-20 years of corrosion protection even in wet environments.
