Teh rolled spindle thread is what makes these jacks actually work smoothly under load, and we've been shippng them for years to US and EU buyers who need consistent quality for their scaffold systems. 2. It's a solid Q235 steel construction in either solid or hollow — the hollow ones are lighter but still handle the same weight, so most buyers go with those for easier handling on site. 3. For compliance, we include the neccessary import docs like COA and packing list, and we've got ISO 9001 and SGS certs on file if your inspector needs them. 4. The base plate runs form 120x120mm up to 150x150mm, and the U-plate is usually 150x120mm to 180x150mm depending on the size you pick — our company can adjust thickness from 4mm to 6mm too. 5. Lead time is typically 20 days or so for a standard order of 1000 pieces, but we usually have stock for the 30mm diameter with a 600mm length in painted finish. 6. One thing buyers don't always think about: the thread pitch is consistent across all sizes, so you can mix and match spindles without issues on site.
Solid jacks are made from a solid Q235 steel rod, so they're heavier and better for heavy-load applications. Hollow jacks use a steel tube, which is lighter and easier to handle, but still strong enough for most construction work. You can pick based on your weight and load needs.
Yes, the standard is silver, but we offer custom colors and surface treatments like painted, electro-galvanized, hot-dip galvanized, or powder coated. Just let us know what you need when you place the order.
The MOQ is 1000 pieces per size and type. Lead time usually runs 2-3 weeks after order confirmation, depending on the quantity and surface treatment you choose.
Absolutely, we can include ISO 9001 and SGS certificates with your order. Just request them when you finalize the purchase, and we'll send them along.
