GLASS STORAGE RACK | PROJECT-NUMBER MODEL GUIDE
A project-number L-frame glass rack needs its own load rating because the verified records are not one standard design. Model 10777 is rated at 750 kg, 10895 at 800 kg, 14792 at 2,000 kg, 15725 at 2,500 kg, and 15742 at 1,000 kg. Project 05205 is recorded at not more than 2,000 kg. The correct glass transport rack must be selected by model, not by a single headline capacity.
For an engineer or buyer searching for glass rack load capacity by model, the first rule is simple: do not merge project records. An L-frame glass holding rack is a configured industrial transport asset. Its rated load is connected to its footprint, base channels, reinforcement, weld design and intended glass arrangement. A compact rack for light or mid-size sheets cannot be represented as the same rack as a long-base unit for heavy architectural glass.
This distinction also separates a reusable L-frame glass rack from an A-frame glass rack or harp rack. Grack uses a single-sided support geometry for wall-side or back-to-back layouts. It can support storage, line-side transfer, truck loading, jobsite delivery and empty-rack return, but each use still requires a check of the model and handling method.
Verified glass rack load capacity by opportunity number
The current model index records 10777 at 750 kg with a 1,200 × 900 × 1,200 mm footprint and about 46 kg self-weight. Model 10895 is 800 kg at 1,180 × 600 × 1,155 mm and about 47 kg. Model 14792 is 2,000 kg at 2,000 × 1,300 × 1,300 mm; its recorded weight is 81 ± 3 kg without rubber and 93 ± 5 kg with rubber. Model 15725 is rated at 2,500 kg in both the single-sided 1,800 × 950 × 1,600 mm form and the separate double-sided 1,800 × 1,150 × 1,620 mm form. Model 15742 is 1,000 kg at 2,400 × 750 × 1,200 mm. The 05205 Canada project is 1,600 × 950 × 1,600 mm and recorded at not more than 2,000 kg, with reinforced joints and a 20 mm raised angle.
Why one capacity and one container count would be misleading
Capacity cannot be standardized across these records because size, support span, reinforcement and configuration change. The recorded loading references show the same issue: 10777 has a reference of 100 units on a 9.6 m flatbed; 10895 has 250 units in a 40HQ per its project file; 14792 records 33 units in a 20GP and 78 in a 40HQ; and single-sided 15725 records 24 units in a 20GP and 84 in a 40HQ. These figures belong to their corresponding geometry and stacking method. They must not be copied to another model. The double-sided 15725 is wider and heavier, so it requires a separate loading calculation. The 15742 and 05205 records do not provide a universal container quantity.
For an actual calculation, buyers should provide rack dimensions, nesting direction, single- or double-sided construction, accessory clearance, container type, securing method and the required working aisle. Empty racks may be nested or inverted for return logistics, but the achievable count depends on the exact frame. Container loading is therefore a geometry calculation, not a reward for choosing a higher load rating.
Match dimensions, protection and options to the work condition
Start with the glass: panel length, width, thickness, total load, center of gravity and whether the load is monolithic, laminated, tempered or insulated glass. Loaded sheets typically sit at about 85°–87°. The support line, back support, aisle and forklift approach must all fit the selected footprint. A longer base may suit oversized panels, while a compact model may be more practical for a constrained line-side area. Neither choice can be inferred from capacity alone.
Grack’s documented configurations use Q235 carbon steel, load-bearing full-seam welding and powder coating. Steel-core rubber protection can be mechanically fixed with screws rather than relying on adhesive alone, helping avoid the peeling risk associated with glued pads under vibration, heat or moisture. Forklift pockets, pallet-jack clearance, lifting pins, retaining bars and tie-down points are project options to verify against site equipment. Casters are not a default feature; select them only when floor condition, route, wheel load, braking and stability have been checked. For sustained outdoor, wet or corrosive exposure, hot-dip galvanizing can be evaluated as a project option, with the coating specification confirmed before production.
Selection checklist for a model-specific glass storage rack
- State the opportunity or model number and keep its verified load, dimensions and self-weight separate from every other project record.
- Submit panel dimensions, glass type, total load, loading angle, separators and retaining requirements so the rack footprint matches the real glass condition.
- Confirm forklift fork width, pallet-jack access, crane lifting points, aisle limits and whether casters are actually required; wheels are not the default.
- Calculate flatbed, 20GP or 40HQ loading from the selected geometry and nesting or stacking method, then review powder coating or hot-dip galvanizing for the exposure.
