Mgrack | Load engineering for glass and panel handling
A Q235A bolted A-frame glass rack is not defined by one “standard” load number. The practical range is typically 1,000–3,600 kg of uniformly distributed rack load by configuration, with the actual per-side figure determined by tube wall thickness, caster package, load position, and handling method.
For purchasing, process, and safety teams, the important question is not simply “Can this rack hold 3 tons?” The correct question is: how much does one panel weigh, how many panels are placed on one side, where is the center of gravity, and will the rack be pushed, lifted, or moved by forklift? Those details define the safe configuration. Mgrack is a double-sided A-frame panel storage rack that can also be configured for single-sided loading, but the quotation must tie the capacity to the order drawing and the declared handling conditions.
Q235A steel provides the material basis for a robust frame. The rack combines welded load-bearing subassemblies with bolted modular connections, allowing the unit to be shipped, assembled, and maintained more efficiently without treating the bolted structure as a weak substitute for welding. Capacity remains a designed value—not a number to select independently from the frame, tube, wheels, and operating method.
What does the 1,000–3,600 kg range actually mean?
The verified product range is a configuration range for uniformly distributed load. It is not a universal standard rating and it should not be copied into a purchase order as “3,600 kg per side” unless the approved drawing states that exact basis. A lower configuration may be suitable for approximately 1,000 kg total rack load, while reinforced versions can be engineered toward 3,600 kg. The difference comes from the complete load path: upright and base geometry, tube wall thickness, welded joints, bolted plates, support spacing, caster selection, and the way panels are restrained.
Per side, single side, or total rack load?
For a double-sided rack, “per side” must be written explicitly. If the buyer loads only one side, the frame sees an asymmetric load and may require a different support, restraint, or operating limit than a balanced two-sided arrangement. If both sides are loaded, the total panel weight and its distribution still govern the design; do not assume that a total figure can be divided equally without engineering confirmation. A single-sided version is useful when the rack is placed against a wall or when the workflow feeds panels from one direction, but it is not automatically equivalent to a double-sided rack.
Two external reference points illustrate why configuration matters, rather than proving a fixed Mgrack rating: one COCHEZ example describes a 1-ton rack at approximately 2,150 × 600 × 800 mm, while a HYPHENATE reference shows a 330 kg light-duty unit with a possible 1–1.5 ton range in other configurations. These are industry examples, not claims that every Mgrack uses those dimensions or ratings. Mgrack capacity must be confirmed against the buyer’s panel dimensions, unit weight, quantity per side, and handling route.
Why a bolted assembly can be as safe as a welded rack
A bolted node is not judged by the word “bolted.” It is judged by the connection design: bolt size and grade, number of fasteners, plate thickness, hole layout, edge distance, joint slip control, tightening method, and the forces carried through the frame. In Mgrack, the load-bearing components are prepared as welded steel assemblies; the modular frame is then joined through designed bolt-on interfaces. This separates repeatable factory welding from field assembly and transport convenience.
The practical proof is therefore the engineering package: the approved drawing identifies the welded components, bolt interfaces, tube wall thickness, caster arrangement, load case, and stated operating limits. The image of the bolted triangular support helps verify the construction approach, but it is not a load test certificate. Buyers needing a formal safety commitment should request the configuration drawing and any agreed calculation or test documentation before release.
What to specify before requesting a load quotation
- Panel load: provide the maximum single-panel weight, panel dimensions, thickness, and the number of panels planned on each side.
- Load basis: state whether the requested 1,000–3,600 kg figure means total rack load, double-sided combined load, or a confirmed per-side load.
- Frame and caster package: ask for the selected tube wall thickness, base design, caster material, wheel arrangement, floor condition, and any brake requirement. Polyurethane casters can support controlled workshop movement, but the caster rating and speed must be matched to the loaded rack.
- Handling method: identify hand pushing, towing, forklift pockets, lifting lugs, floor slope, aisle width, and whether the rack is stationary during loading. These factors are part of the safe use case, not after-sales details.
