When your crew is setting up on uneven terrain for a bridge pier or tunnel portal, what you really need is something that can take the load without shifting—these base jacks do that, with solid or hollow thread options depending on whether you're after raw strength or lighter handling, and the Q235 steel core means they'll hold up under heavy scaffold frames day after day.
We've been shiping these for years now, and the 34mm solid thread version is pretty much go-to for most building sites, though the 30mm hollow thread is easier to spin down by hand when you're adjusting on the fly, and the 48mm size handles those big U-head plates (180x150x50x5mm) better than the smaller base plate options for heavy bridge work.
Lead time is typically 20 days or so for a standard MOQ of 1000 pieces, but if you need hot-dip galvanized finish or a custom length like 1000mm, we usually have stock but confirm lead time—teh powder coated option actually holds up better in wet climates, but electro-galvanized is cheaper if you're not worried about corrosion.
One thing most buyers don't think to ask is that the thread pitch on the hollow type is slightly coarser (roughly 6mm vs 8mm on solid), which means faster adjustment but a bit less fine-tuning—it's not a problem for general scaffolding, but for precision leveling on a tunnel formwork, you'll want the solid thread every time.
ISO 9001 and SGS certs are standerd, and our company can provide a COA with HPLC data if you need it for your quailty audit, though the real test is just cranking one down on a test frame—the Q235 steel holds a consistent yield strength across batches, and the pipe construction means no weld weak points at the base plate joint.
Solid thread means the thread is machined directly onto a solid steel rod — stronger but heavier. Hollow thread uses a pipe with threads rolled on, which is lighter and often easier to adjust on site. Both work for scaffolding support, so pick based on your weight and ease-of-use needs.
Yes, hot-dip galvanized is one of our surface treatment options, along with painted, electro-galvanized, and powder coated. Hot-dip gives the best corrosion protection for outdoor or wet job sites.
We provide ISO 9001 and SGS certificates with each order. These cover our production quality and material standards, so you can verify compliance easily.
Yes, we can combine any of the length options (500mm, 600mm, 800mm, 1000mm) with any of the thread sizes from 28mm up to 48mm. Just specify when ordering.
Minimum order is 1000 pieces. Lead time usually runs 15-20 days after order confirmation, depending on the customization and surface treatment you choose.
