We own complete in-house production lines including stamping, thread rolling and hot-dip galvanizing without outsourcing any working procedure. Adhering to Q235 & Q355 high-strength carbon steel raw material, precision thread rolling technique and thickened load-bearing base plate, our Base Jack complies with EN12811 & BS1139 European standards. A full range of standard specifications are kept in stock, custom non-standard sizes and OEM branding are available. HDG finished items perform excellently under coastal saline and harsh outdoor construction conditions, making us the preferred one-stop supplier for global construction contractors and scaffolding wholesalers sourcing matched Base Jack and U Head as complete shoring sets.
Product Introduction & Working Principle
Also named adjustable leveling jack or screw base jack,Scaffolding Base Jack is the core load-bearing component installed at the bottom of ringlock, cuplock, frame scaffolding and adjustable formwork props, paired with U Head mounted on the top to form a full shoring system. By rotating cast adjusting nuts to lift or lower the screw, construction crews level uneven ground flexibly, evenly disperse vertical loads of scaffolding and formwork, prevent frame settlement or tilting and effectively eliminate potential construction safety risks. It is a mandatory fitting for cast-in-situ floor and beam formwork projects worldwide.

Five Core Product Selling Points
Stable Load Performance
One-piece stamped thick base plate expands grounding area to avoid partial sinking; precisely rolled screw thread ensures tight meshing with nuts, anti-slip and anti-breakage under heavy load
Long-lasting Anti-corrosion
Hot-dip galvanizing delivers uniform zinc coating; its anti-rust service life is over 3 times longer than paint or electro-galvanized items, cutting clients' repeated replacement cost for cyclic site use
Wide Compatibility
Inner diameter fits standard 48.3mm scaffold tube universally, perfectly matching ringlock, cuplock, frame scaffolding and formwork props. Supporting our U Head together to finish complete shoring procurement in one order
High Construction Efficiency
Thick cast handwheel nut brings smooth rotation, enabling fast height adjustment on site to save labor cost during frame leveling Flexible Customization
Flexible CustomizationIn-house mold workshop supports non-standard base plate, extended screw and swivel base jack development; both small trial orders and bulk mass production are acceptable
Application Scope
Our Scaffolding Base Jack is widely used in high-rise residential buildings, commercial complex heavy shoring, bridge engineering, subway construction, factory renovation, dock infrastructure and shipbuilding projects, exported to Europe, Southeast Asia, Middle East and Australia for cast-in-place concrete formwork and external scaffold leveling.

FAQ Section
Q1: Solid screw or hollow screw base jack, which to choose?
Hollow screw Scaffolding Base Jack is cost-effective for low-rise residential and light-duty shoring; solid screw version is recommended for high-rise buildings, bridge and heavy-load projects with superior bearing capability.
Q2: Difference between HDG and electro-galvanized finish?
Hot-dip galvanized Scaffolding Base Jack is ideal for coastal, rainy and humid construction sites with over 5 years anti-corrosion lifespan; electro-galvanized or painted options suit inland dry projects for better cost control.
Q3: Can your base jack cooperate with third-party U Head?
Our products follow international universal dimensional tolerance, compatible with most regular U Head on the market. Full-set U Head + Base Jack from our factory guarantees tighter assembly and better matching precision.
