If you are sourcing scaffolding components for a project, one of the first questions you will ask is what a U-head jack costs. For buyers comparing quotes from Chinese suppliers, the honest answer is that the current u head jack price per piece from Tianjin factories typically falls somewhere between roughly US$2 and US$13, depending on the screw bar diameter, length, whether the jack is solid or hollow, the surface treatment, and the order quantity. This guide explains what you are actually paying for, why prices differ so much between suppliers, and how to get a quote that reflects the real cost of the jack you need.
What Is a U-Head Jack and Why Does Its Price Matter?
A u head jack is an adjustable support that sits on top of a scaffold standard or prop to carry beams, formwork, or timber. It is made of three main parts: a threaded screw bar, a U-shaped head plate that cradles the load, and a nut that locks the adjustment in place. Because the threaded portion has to be machined and the head plate welded, a U-head jack carries more fabrication cost than a plain tube, and that is the first reason prices vary so much between suppliers.
U-head jacks are used across modular systems, including ringlock, cuplock, frame scaffolding, and tube and clamp setups, as well as in bridge construction and heavy formwork work. They are the top-end counterpart of the base jack, which does the same job at the bottom of the structure. When you price a U-head jack, you are pricing the part that transfers the load from the deck above into the scaffold below, so the specification has to match the loads your project actually carries.
Current U-Head Jack Price Per Piece from Tianjin Factories
Based on current listings from Chinese B2B platforms, here is a realistic picture of what U-head jacks cost per piece from factories in the Tianjin area:
- Small solid jacks with a 28–32 mm screw bar and shorter lengths: roughly US$2–5 per piece.
- Standard jacks with a 34–38 mm screw bar: roughly US$4–8 per piece.
- Hollow jacks or larger heavy-duty versions with hot-dip galvanizing: roughly US$6–13 per piece.
These are indicative ranges, not fixed prices. Steel prices move with the market, and the same jack can cost noticeably more or less depending on the specification and the volume you order. What the ranges show is that per-piece pricing is driven far more by specification than by the factory’s location.
What Drives the Price Per Piece
Before you compare quotes, it helps to know which specification choices move the number. These are the factors that have the biggest influence on the per-piece price:
- Screw bar diameter and length: A 28 mm bar costs less than a 38 mm bar, and a 600 mm jack costs less than a 1000 mm one. Longer, thicker bars mean more steel and more machining.
- Solid vs hollow: Solid jacks use a full threaded bar and are generally cheaper to produce at smaller sizes; hollow jacks fit over a standard and are common in heavier applications.
- U plate size and thickness: The head plate that carries the load is often customized. Larger plates and thicker steel, sometimes reinforced with welded triangular ribs, add cost but raise the safe working load.
- Surface treatment: Hot-dip galvanizing costs more than electro-galvanizing, painting, or powder coating, but it gives the best corrosion protection for outdoor and coastal sites.
- Steel grade: Q235 is the standard grade for most jacks; Q355 offers higher strength for heavy-duty work.
- Quantity and MOQ: Per-piece price drops as volume rises. Most Tianjin factories quote a base price at their minimum order quantity and step the price down for larger lots.
- Packaging and delivery: Palletized packing and container loading are usually included, but they still factor into the final per-piece figure.
Why Buy U-Head Jacks from Tianjin Factories
Tianjin is one of China’s most important steel and scaffolding manufacturing hubs. The city sits close to raw steel production in northern China and to Tianjin Port, one of the busiest container ports in the world, which keeps export freight costs and lead times competitive. That combination of material supply and port access is why so many scaffolding suppliers base their production there, including Bythai Scaffolding Co., Ltd., whose factory is located in Daqiu Zhuang town, Tianjin.
Buying from a Tianjin factory also means you can deal directly with the manufacturer rather than a trading intermediary, which usually translates into better per-piece pricing and more control over quality. Bythai, for example, manufactures its U-head jack for tube and clamps systems from Q235 steel in an ISO 9001 certified facility, with products made to international EN and BS standards and surface treatments ranging from electro-galvanized to hot-dip galvanized.
How to Get an Accurate Per-Piece Quote
To get a quote you can actually compare, send suppliers a clear specification rather than just asking how much a U-head jack costs. Include the following details:
- Screw bar diameter and length, for example 38 mm × 600 mm.
- Solid or hollow type.
- U plate size and thickness, or the load you need to carry.
- Surface treatment and steel grade.
- Quantity and delivery destination.
A reputable supplier will confirm the specification, state the MOQ, and quote per piece at your volume. Ask for the batch test report and certificate with the quotation, and check that the factory can back its price with consistent quality across orders.
