RFQ checklist / Mobile glass rack
Lock the panel size, working weight, handling route, finish, and return packing before you request a quote. Mgrack is project-based, so the RFQ must be project-based too.
When buyers ask for a mobile glass rack quote with only a rough size, the answer is usually the wrong rack. Mgrack is a double-sided A-frame storage and transport asset for glass, photovoltaic panels, granite, stone slabs, doors, windows, and similar sheet goods. It is built to support upright storage, in-plant transfer, and empty-rack return logistics, not to act like a one-time wooden skid or a fixed warehouse rack.
The design choices change with the route. A rack that rolls on casters, enters by forklift, or moves with lifting lugs does not share the same base geometry, contact protection, or loading pitch. Project records show Q235A carbon steel, bolted knock-down assembly with welded subcomponents, and static powder coating as the common finish, while hot-dip galvanizing appears in some project-specific notes. That is why the RFQ should start from the panel and handling route, then work back to the rack.
1. Confirm the panel geometry and working weight
The first question is not “what rack size do you have,” but “what panel family are you handling.” Confirm the exact length, width, thickness, maximum unit weight, and whether the load is glass, stone, PV modules, or doors and windows. If the panel edge is polished, coated, or brittle, say so in the RFQ. The rack pitch, contact zone, and restraint points must follow the product, not the other way around.
The archive does not support a single universal size. It contains project examples such as 1500×1000×1500 mm, 2400×1120×2385 mm, 1878×1100×1601 mm, 2400×1120×1800 mm, 2150×600×800 mm, and 1100×1200×2500 mm. Storage widths in the records also vary around 210 mm, 350 mm, and 420 mm depending on the panel family. Those figures are reference points, not a fixed SKU.

Protection details matter as much as footprint. The visual record shows steel-embedded rubber pads and strip protection at the contact area, which is the right direction for glass and polished stone. If the RFQ does not define the contact material, a supplier may default to bare steel contact or a pad position that does not match the panel thickness. Ask for the contact finish explicitly, especially if the load is low-iron glass or a surface that scratches easily.
2. Choose the handling method before you choose the frame
Handling method changes the whole rack. For short internal transfers on a smooth plant floor, casters are usually the right answer, but the RFQ should still define wheel size, wheel material, brake requirement, and turning radius. The archive shows 5-inch and 6-inch caster setups, with both fixed and swivel-brake mixes, plus polyurethane or iron-core polyurethane wheel options. Those details are not cosmetic; they decide whether the rack will roll, stop, and turn the way the plant actually works.
If the route includes forklift pickup, the RFQ must specify whether entry is two-way or four-way, because the fork opening is a design choice, not a universal standard. If the rack will ever be lifted overhead, ask for lifting lugs or hooks as a project-specific option instead of assuming they are included. In many plants, the correct answer is not “use every handling mode,” but “use the one handling mode the route really needs.” That keeps cost, weight, and interference down.
3. Calculate empty return and container load before you sign
The rack is also a logistics asset. Mgrack is often shipped knock-down, then nested and stacked when empty, which means the empty-return plan should be part of the RFQ from day one. If the buyer only asks for a working rack and ignores return routing, the final answer may be expensive to ship back. That is especially important for overseas buyers who need reusable returnable racks and high container density.
The records include container-loading examples, but they are project examples, not a promise. For reference only, recorded 20GP examples include 36 and 60 sets, while recorded 40HQ examples include 90, 144, and 180 sets. Final loading count depends on final footprint, height, nesting depth, padding, and whether the rack ships as parts or as a fully assembled unit. Stretch wrap plus strapping is common; wood crates can protect appearance better, but they reduce loading quantity and add cost.

The nested empty-rack photo is the real reason to ask the shipping question early. If the racks must return, tell the supplier how many empties can be stacked, what the return route looks like, and whether the empty units must travel in a container or on a truck deck. If the rack is one-way export only, say that too. One-way export and returnable logistics are not the same business case, and they should not be quoted as if they were.
RFQ checklist
- Panel length, width, thickness, material type, maximum unit weight, and edge-sensitivity.
- Handling route: casters, forklift, or lifting lugs; aisle width, floor condition, slope, and turning radius.
- Protection and finish: rubber pads, limit rods, ratchet straps, powder coat, or hot-dip galvanizing.
- Packing and return: KD shipping, empty nesting target, container target, and one-way or returnable use.
