For heavy lifting where failure isn't an option, we've dialed in the forging process to eliminate weak points—hot-dip galvanized steel gives you a zinc layer that holds up in salt spray for years, and stainless steel is better for food-grade or chemical washdown environments where you can't have any rust risk.
The working load limit ranges form 100kg to 40,000kg depending on the size you pick, and we test every single unit with a 100% inspection protocol that includes a proof load at 1.5x WLL using a calibrated hydraulic press—basically, if it cracks or deforms during that, it's scrapped, not sold.
What you're getting is a right-hand and left-hand threaded screw mechanism that lets you adjust tension without disconnecting the load, and the end configurations (jaw-jaw, eye-eye, or hook-hook) mean you can match it to your existing hardware without custom adapters; the lock nuts or safety pins prevent any backing off under vibration, which is critical for stage rigging or marine applications where you can't have a turnbuckle loosening mid-show.
For OEM runs, we can tweak the thread pitch or suface treatment—electric galvanizing is cheaper but thinner, while hot-dip is what most buyers go with for outdoor use—and we usually have stock on common sizes like 1/2-inch or 3/4-inch, but for something like a 2-inch with a 40-ton limit, confirm lead time (usually 4-6 weeks) because we cast those to order.
One thing that catches people off guard is that teh left-hand threaded side can be a pain if your crew isn't used to it—we mark the turnbuckle body with a groove on the left-hand end, so there's no guessing during insallation, but you'll still want to train them on the direction.
Storage is straightforward: keep them dry and off the ground, and the galvanized finish won't need any special treatment, but if you're in high-humidity warhouse, a light oiling on the threads every six months or so keeps the adjustment smooth—just don't use grease because of that it traps grit.
For custom setups like jaw-jaw with specific thread types, our MOQ is typically 500 pieces per size. Standard catalog items may have lower minimums—just let us know your specs and we’ll confirm.
Yes, we supply mill test certificates and can arrange third-party inspections like ABS or Lloyd’s if needed. Just specify the cert requirements when you place the order, and we’ll include them.
For standard sizes with left-hand threads, lead time is around 25-30 days after order confirmation. Rush orders are possible if we have stock, but custom forging takes the full cycle.
Every unit gets a manual check—lock nuts are torqued to spec and safety pins are fitted to verify retention. We also batch-test random samples for pull-out force to ensure they hold under load.
Sure, we can polish stainless steel hook-hook ends to a bright finish for stage use. Just note that polishing adds about 3-5 days to production, and it’s best to confirm the surface prep level when ordering.
