You're on a tight site where the ground isn't level and you need to get your scaffolding plumb fast—adjusting height with stacked timber or shims takes forever and introduces risk, so a screw jack lets you dial in that exact elevation with a few turns, and it's pretty much the standerd solution for any formwork or access system.
What our company supply here is a steel base jack that handles that load transfer and height adjustment, and teh whole thing is built around a threaded screw tube and a nut assembly that we've found holds up well under repeated use, though the exact longevity depends on how rough the crew is with it.
They come in two main configurations—solid type with diameters of 30mm, 32mm, or 34mm, and hollow type with a 38x4mm or 48x5mm tube—and for the solid ones base plate is typically square, but you can also get a U-head if that's what your system needs, and the standard lengths are 500mm or 600mm, which covers most appliction.
We do offer a choice between electro-galvanized and hot DIP galvanized surfaces, which basically means you can match the finish to your site conditions, and the hot DIP is better than electro for long-term outdoor exposure, though it adds a bit to the cost.
For shipments to the US, EU, or UK we handle all the import paperwork, and the HS code is 73084000, so you'll clear customs without a headache—just two or three weeks for lead time typically, but confirm before you place the order.
Our MOQ is 500 pieces per size and type, but we can discuss sample orders for testing. Just let us know your requirements.
We provide mill test certificates for the Q235 steel and can issue a third-party inspection report for the galvanized coating, either electro or hot dip, upon request.
Yes, we can adjust the screw jack length and base plate dimensions to your specs. Just share your drawings or required measurements, and we'll confirm feasibility.
For the 38x4mm hollow type, the outer diameter is 38mm with a 4mm wall thickness. The 38x5mm version has a 5mm wall, and the 48x5mm has a 48mm outer diameter with a 5mm wall.
They're packed in pallets with steel strapping and waterproof wrapping. Store them in a dry, covered area to keep the galvanized surface in good condition, especially the electro-galvanized ones.
