If you are managing a Glass Distributor center or a fabrication plant, you know the math: sending glass out is revenue; bringing empty racks back is pure cost. Standard welded A-frames are notorious space hogs.
The L-Shape design (often called the "L-buck" or "Grack") changes this equation through Nesting Capability. Because the base is geometrically calculated with an open front and a tapered rear, these racks slide into one another when empty.
The Efficiency Metric: You can stack and nest empty L-racks to reduce their volume by over 70%. In a standard 40HQ container or a flatbed trailer, you can fit up to 98 to 112 units (depending on the model). This transforms them from a sunk cost into a highly efficient Returnable Shipping Rack system.
Empty L-racks nesting like shopping carts, saving 70% of warehouse and truck space.
In the wholesale tempered glass business, a microscopic scratch on the Low-E coating or a minor shell chip on the edge renders the sheet useless. The culprit is often the storage rack itself.
Cheap generic racks use glue to attach rubber pads. In hot climates (like California summers) or under the shear force of loading heavy Insulated Glass Units (IGU), that glue fails. The rubber slides off, and your glass meets bare steel.
Our Engineering Solution: Steel-Core Rubber Profiles.
Mechanically fixed steel-core rubber protecting IGU edges from steel contact.
Whether you are handling raw float glass or finished laminated sheets, weight is the constant challenge. A rack that flexes under load is a rack that breaks glass.
We utilize Q235 Carbon Structural Steel (equivalent to ASTM A36). The main load-bearing uprights are typically 50x50mm or 60x60mm square tubes with a wall thickness of 2.5mm+. We do not use "stitch welding." Every joint is Full Seam Welded to ensure the frame acts as a single rigid body.
Furthermore, the base is designed with dedicated Forklift Channels (rectangular tubes, often 100x50mm) to prevent fork damage during the thousands of lifting cycles in your warehouse.
Reinforced base structure with dedicated forklift channels for safe 4-way entry.
Space is money. Double-sided A-frames require access from both sides, often demanding wide aisles in the center of your facility. The Single-sided Glass Rack design allows you to place inventory directly against walls or back-to-back.
This "L" configuration, combined with a scientifically calculated 3-5 degree tilt angle, ensures that glass sheets rest naturally against the back supports without the risk of tipping forward. For added safety during empty transport or uneven flooring, our models include rear counter-weights to keep the center of gravity low and stable.
Back-to-back placement maximizes floor space efficiency in tight warehouses.
1. Can I mix these L-racks with my existing A-frames for shipping?
While you can load them on the same flatbed, they cannot stack on top of A-frames. However, the L-racks are designed to nest with each other for the return trip, which frees up deck space on your trucks.
2. What is the standard angle of the uprights?
The standard tilt is between 85° and 87° (3° to 5° from vertical). This critical angle uses gravity to keep the glass sheets (lites) stable against the rubber pads without putting excessive stress on the bottom edge.
3. We handle Jumbo size sheets (130" x 204"). Can you customize dimensions?
Yes. While the standard container-optimized unit is approx. 63" (1600mm) long, we manufacture Heavy Duty Glass Racks stretched to 2032mm (80") or longer with increased weight capacity (up to 4 tons) for architectural jumbo glass.
4. How do you prevent the racks from rusting in outdoor stone/glass yards?
For indoor use, we use an electrostatic powder coating (RAL 5010 Blue is standard). For outdoor storage exposed to rain or humidity, we recommend Hot-Dip Galvanizing, which provides a metallurgical bond zinc coating that lasts 10-20 years without rust.
5. Are the rubber pads replaceable?
Absolutely. Because we use screws instead of glue, your maintenance team can swap out a worn rubber strip in minutes using a standard impact driver, keeping your asset protection level high.
