our company can produce this with Q235 or Q355 steel depending on your load requrements, and the base plate holes are punched consistently within ±1mm across each batch — we measure every 50th piece off the line to catch drift.
Testing covers two main things: dimensional checks on the thread pitch and the slip load at full extension, and we also pull a random sample per 1,000 units for a simulated construction load test (roughly 1.5x the rated capacty) to confirm weld integrity on hollow types.
Our standerd COA covers tensile strength for the rod stock and a pass/fail for the zinc coating thickness on hot dip (85µm minimum required), but if you need the full SGS batch cert with retest parameters we can email those within 2 days of the QC stamp.
Most of what we ship goes out under EN74 compliance with a TUV-notified body marker on the cast nut, but for petrochemical jobs the spec sheet they want usually includes the CE declaration — our company have both files ready to attach.
One thing buyers ask about is retesting if a batch fails — we do a 2X resample form the same lot within 24 hours and cover retest cost ourselves, and this has only come up twice in the last three years.
On a typical 1,000-piece MOQ we batch certify three tensile coupons and three weld samples (solid types skip the weld step), and we can print your logo onto the base plate or the hex nut depending on the surfce finish — paint takes a week more than electro galvanized on customization.
Our MOQ is 1000 pieces per size and type. That covers solid, hollow, or U-head versions, and you can mix different specs within that quantity if needed.
Yes, base plate dimensions are customizable. Just let us know your exact size, and we'll adjust production accordingly.
We have CE and SGS certificates, and all models comply with BS1139 and EN74 standards. We can share the docs with your order.
Standard lead time is 15-20 working days after order confirmation and deposit. Custom logo and packaging don't add extra time as long as the artwork is approved upfront.
Hot dip galvanizing offers the best corrosion resistance for wet environments. If you need less protection but lower cost, electro galvanized works well for indoor or short-term jobs.
