We see these things coming in from other suppliers with mismatched thread pitches or undersized base plates, and that’s where the real headache starts—our Q235 jacks are batch-tested for dimensional consistency under EN74/BS1139, so you’re not inheriting a field problem. Load capacity is high, sure, but what matters is we actually retest random samples from each production run, not just the first batch off the line.
Thread rod diameters run 30mm to 48mm with adjustable heights from 400mm up to 1000mm, and both solid and hollow options are avaliable depending on your weight tolerance; we usually recommend the hollow variant for tower systems to keep handling lighter. Base plates come in 120x120mm or 150x150mm with plate thicknesses of 4mm, 5mm, or 6mm—go with 6mm if you’re stacking multiple tiers, though honestly 5mm does fine for most residential formwork builds.
Surface treatment matters more than some buyers realize: hot-dip galvanized lasts years longer in coastal environments than black paint, but we always include SGS-tested zinc thickness data on the COA (anyway, lead time for hot-dip is about 2 weeks, give or take). We hold CE and ISO certifications, so your compliance audit is covered—though I’d suggest asking for the test cert on nut rotation torque if you’re using forged nuts instead of cast ones.
U-head jacks for formwork support are our most popular variant for shoring applicaion—they hold wooden beams securely without slipping, and the cradle depth is deeper than you’ll get from off-brand units (basically, we mill the opening to spec rather than just stamping it). It’s not the right choice for heavy bridge falsework though; for that you’ll want solid base jack with teh 45mm rod, but that’s a separate conversation.
Lead time on standard sizes (32mm rod, 400mm travel, painted) is typically 7 to 15 days, and MOQ is flexible down to about 50 units or so for trial runs—we bulk-pack on steel pallets unless you prefer individual strapping. OEM branding is available: just send your bolt circle drawing if you need a custom base plate hole pattern, and we adjust thread lengths to match your cup socket depth within roughly 5mm tolerance.
We stock diameters from 30mm up to 48mm, and the adjustable length range is 400mm to 1000mm — but yes, we can customize that further to match your formwork needs.
Absolutely — all our heavy-duty U-head jacks come with CE, SGS, and ISO certifications, so you're covered on quality and compliance for international projects.
For standard items, lead time is 7-15 days, and our MOQ is flexible — we can negotiate based on your order volume, so just let us know what you need.
Sure, we offer hot-dip galvanized, electro galvanized, or black paint finishes. For export, we pack them on steel pallets or do bulk packing — whichever keeps your freight costs down.
Yes, they're designed to work with Ringlock, Cuplock, Kwikstage, and Tube & Clamp systems, so you can use them across different scaffold setups without compatibility issues.
