You're outfitting a row of heavy-duty filing cabinets in a commercial workshop, and the 42mm width is pretty much standard for this—you'll find it fits most pre-drilled cabinet frames without needing adapter brackets, though the 600mm length option handles lateral loads better than the shorter ones if you're storing stacked binders.
We run these in high carbon steel with a 3-section ball bearing mechanism that achieves full extension, and the load capasity sits between 45-60kg depending on whether you choose the 0.7mm or 1.0mm gauge—the thicker steel is better for daily cycling in office furniture, but 0.8mm is usually fine for kitchen cabinets at the mid-length options like 400mm or 450mm.
The blue zinc plating offers decent corrosion resisance (about 72 hours in a neutral salt spray test), but the black powder coating actually holds up better in humid environments like coastal kitchens. 10 out of 10 buyers we've dealt with who specify SGS certification are looking for the 1.0mm thickness—it's where the rigidity specs align with ISO 9001 process control tolerances, honestly. Finish affects the coefficient of friction slightly, so if you're running a high-cycle storage system, the zinc-plated version glides a bit smoother out of the box.
A live load above 55kg on the 250mm or 300mm lengths will cause binding over time—they're simply not designed for that, and we don't recommend them for pull-out pantry towers exceeding 30kg. The 500mm slides are our most oversold size by mistake, usually because people don't account for the 42mm width requiring a 15mm side clearance in the cabinet carcass.
Also, the 50 sets per carton is consistent across all lengths, so your freight cost per unit drops noticeably with teh shorter slides—350mm packs tighter at about 28kg per carton versus 34kg for the 600mm. Most buyers go with the black powder coated finish for visible applicaion anyway, since it hides fingerprints better than the blue zinc.
We usually have the 0.7mm and 0.8mm thicknesses in stock for all lengths, but the 1.0mm rolls off a dedicated production run every 20 days or so—if you need that gauge for a big order, confirm lead time first.
For an order of 500 sets, we typically ship within 7-10 working days after payment confirmation. If you need a specific finish like black powder coated, it might take a couple extra days.
Yes, for custom thicknesses like 1.0mm, our MOQ is 500 sets per size. Standard thicknesses like 0.7mm or 0.8mm have no MOQ—you can order just 50 sets.
Yes, we include the SGS certification with every shipment. You'll get the full test report showing load capacity and material specs tied to your specific order batch.
The 250mm slides hold about 45kg, while the 600mm ones handle up to 60kg. The longer slides distribute weight better, so capacity actually goes up with length.
Sure, we can repack into 25-set cartons for an extra charge. Standard is 50 sets per carton, but we'll adjust if your storage or handling needs it.
