Is Your Current Racking System Crushing Your Profit Margins? For glass fabricators and distributors, the "cost of doing business" shouldn't include a 5% breakage rate due to flimsy dunnage or unstable A-frames. Whether you are handling heavy architectural jumbo sheets or delicate 1/4" tempered lites, you need a heavy duty glass rack that guarantees zero metal-on-glass contact and optimizes your truck density. |
When we talk about a 2000kg (4400 lbs) Load Capacity, we aren't just talking about the tensile strength of the Q235 carbon steel. We are talking about the structural integrity required to transport stacks of heavy Insulated Glass Units (IGUs) or 19mm monolithic float glass over potholes and around sharp corners without the rack twisting.
In the glass business, rack deflection is the enemy. If your rack flexes during a forklift transfer, the glass takes the stress. The result? "Runners" (cracks) starting from the edge or catastrophic shelling.

The most common failure point in generic glass transport racks isn't the weld—it's the rubber profile. Traditional racks often use glue to attach rubber pads. In the summer heat of a flatbed truck, that glue melts, the rubber slides off, and you get metal-on-glass contact.
Our Solution: Mechanical Fixation.

For glass wholesalers supplying regional glaziers, the headache is the return trip. If you send out 10 racks of glass, you have to bring 10 empty racks back. With traditional A-frames, that takes up the same amount of floor space on the truck. You are literally paying freight to ship air.
Our Nestable L-Rack Design changes the math.
Because of the asymmetric L-shape and the specific geometry of the base, empty racks can slide into one another (nesting) like shopping carts.
Figure 3: Nesting capability allows empty racks to be compressed for storage or return shipping, drastically lowering logistics costs.
We don't guess on specs. Every rack is built to withstand the rigors of an industrial glass fabrication plant and the unpredictability of construction site deliveries.
| Attribute | Specification Detail |

| Tube Dimensions | 50x50mm / 60x60mm Square Tube (Uprights); 100x50mm Rectangular Tube (Base) |
| Load Capacity | Standard 1500kg - 2000kg (Customizable up to 4000kg for Jumbo sheets) |
| Glass Angle | 3° to 5° Tilt (scientifically calculated to prevent forward tipping while minimizing static stress on the rear lite) |
| Surface Treatment | Electrostatic Powder Coating (RAL 5010 Blue) or Hot-Dip Galvanized for outdoor storage |
| Handling | 4-Way Forklift Access + 4 Top Crane Lifting Lugs |
A rack must be versatile. It starts at your sealing robot or tempering furnace unloading station. It gets moved by a pallet jack to the staging area. It gets loaded onto a curtain-sider or flatbed by a forklift. Finally, it might be lifted by a tower crane at a high-rise project.
Our racks feature:

Q1: Can these racks hold mixed sizes of glass, or only uniform sheets?
A: Yes, they can hold mixed sizes. However, for safe transport, we recommend placing larger lites at the back and smaller ones in front. We also offer "stop bars" or securing poles to prevent smaller pieces from shifting sideways.
Q2: My warehouse is humid. Will the racks rust and stain the glass edges?
A: Standard racks are Powder Coated which offers good indoor protection. If you store glass outdoors or in high-humidity areas (where "storage stain" or iridescence is a risk), we strongly recommend our Hot-Dip Galvanized option, which provides 10+ years of rust protection.
Q3: What is the maximum sheet size for the standard L-Rack?
A: The standard model (1600mm long) handles sheets up to 2440mm x 3660mm (standard stock sheets) comfortably with overhang. For Jumbo sheets (3.2m x 6m) or PLF (Primitive Large Format), we manufacture a specific "Jumbo L-Rack" with reinforced base beams.
Q4: How many empty racks can I fit in a 40HQ container?
A: Thanks to the nesting design, a standard 40HQ container can hold approximately 98 to 112 units of our standard L-rack. This is significantly higher than non-nestable A-frames.
Q5: Can I replace the rubber pads if they wear out over time?
A: Absolutely. Since we use screws instead of glue, your maintenance team can simply unscrew the old worn profile and screw in a new one in minutes. No scraping glue or surface prep required.
