Get your scaffolding level even on roughest site with these adjustable U-head base jacks, and we're talking about a solid 4.75mm wall thickness in Q235 steel that handles the load without bending. Basically, you’re getting a threaded rod with a cast nut and bottom plate that adjusts from 100mm up to a meter depending on the diameter you choose — 30mm to 48mm options cover most needs. Most buyers go with the 34mm solid version for general construction, but the hollow ones are lighter. Each piece weighs between 2.6kg and 4.2kg.
We run every batch through our own testing protocols, not just a single COA, and that’s where the CE and SGS certs come from — they're not just paperweights. The surface treatment matters for corrosion resistnce, whether you pick black paint, electric galvanizing, or hot dip galvanizing for harsher environments. It complies with EN74 and BS1139, so you’re covered for most internatioanl specs. But if you’re planning to use these as primary load-bearing supports in seismic zones, they’re better suited for temporary scaffolding than permanent structures — that’s a real limit.
Compatibility is pretty wide — ringlock, cuplock, kwikstage, Haki — so you won’t be stuck with one system. 3D model design is available if your project needs a custom layout, and our company can match any color you want (usually with a lead time of 20 days or so). 100pcs is the MOQ, and we typically stock common diameters like 32mm and 38mm, though the thicker ones may need a production run. And our company offer a 3-year warranty, which is better than most standard construction hardware.
Here’s something a buyer might not think to ask — we keep a retest policy for any batch where the HPLC or dimensional checks show even a slight drift, so you’re not stuck with out-of-spec product. We've seen issues with cast nuts cracking on cheaper imports, but ours are hot-forged and tested to about 50 cycles or so. It’s a detail that’s saved a few clients from site delays.
Also, the adjustable length range (100mm to 1000mm) covers most uneven ground scenarios, but if you need longer than that, tell us upfront — we can customize but it’ll add 2-4 weeks to delivrey. Ordering is straightforward: confirm diameter, surface finish, and quantty, and we’ll send a proforma with the lead time roughly stated.
Our MOQ is 100 pieces per size and type. If you need a smaller trial batch first, talk to our sales team — sometimes we can work something out for new customers.
Yes, we offer free 3D model design based on your project drawings. Just send us the details, and our engineers will create a custom layout for you.
It works with Ringlock, Cuplock, Kwikstage, and Haki systems. If you're using another brand, check the diameter and thread specs — we can probably match it.
We have black paint, electric galvanizing, and hot dip galvanizing. For long-term outdoor or wet conditions, hot dip galvanizing gives the best corrosion protection.
Typical lead time is 15–20 working days after order confirmation and deposit. Hot dip galvanizing takes a bit longer than paint or electric galvanizing, but we'll confirm exact timing when you place the order.
