Scaffolding & Shoring
Temporary works must hold firm from start to finish. GV supplies the steel components that make it possible: cuplock standards and ledgers for system scaffold, steel planks for working decks, base jacks and heavy U-head jacks to level towers, adjustable props with their pins, nuts and threaded tubes for formwork, and trench struts to hold excavations open. We source each part to the size series and standard your project requires.

Where it's used
Temporary works for every stage of a build.
Facades, towers and access
Building facades, plant rooms, tanks and stair towers all need safe access at height while the work goes on. System scaffold goes up fast in regular bays and takes a full working deck at each lift. Cuplock System, Planks and Screw Jack with Base Plate & Wing Nut cover it.
Slabs, beams and formwork
Wet concrete has to be carried until it can carry itself, and the slab above often needs back-propping while the next floor is poured. Props set to height under the formwork do that job, floor by floor. Props, Threaded Tube, Prop Nut and G Pin cover it.
Falsework and heavy shoring
Bridge decks, transfer slabs and high ceilings need taller, heavier support than a single prop can give. Towers built with adjustable jacks top and bottom carry the beams that hold the formwork. Hi-Load Screw Jack with Wing Nut, Screw Jack with Base Plate & Wing Nut and Cuplock System cover it.
Trenches and excavations
Drainage runs, utility trenches and pit excavations must be kept open while people work inside them. Struts set across the trench hold its sides back against the ground. Trench Struts and G Pin cover it.
Hire fleets and spare parts
Hire companies and contractors keep large fleets of props running, and pins go missing and nuts wear. Spare parts made to the same size series keep every prop in use. G Pin, Prop Nut and Threaded Tube cover it.
Scaffolding and shoring systems
Five systems these parts build.
CUPLOCK
Cuplock system scaffold
Standards carry cups every half meter, and each ledger and transom locks into a cup node with no loose fittings. Bays of 0.6 to 3.0 m go up in regular lifts on base jacks.

Questions answered
Common questions about scaffolding and shoring parts.
What do prop sizes 0 to 4 mean?
Sizes 0 to 4 are a standard series of adjustable steel props, each covering a band of heights. Size 0 runs from about 1.1 to 1.8 m and size 4 from about 3.2 to 4.87 m, with sizes 1, 2 and 3 in between. GV supplies props, pins, nuts and threaded tubes to this series to support US contractors and hire equipment fleets.
What does the G pin do on a prop?
The G pin passes through a hole in the prop's inner tube and rests on the prop nut, which sets the coarse height. Its hooked shape keeps it on the prop between uses. The nut is then turned on the threaded tube to bring the prop to its final height.
What is the difference between a base jack and a hi-load screw jack?
A base jack sits under each scaffold standard on a square base plate and levels the scaffold on uneven ground. A hi-load screw jack has a larger stem and usually a U-head or fork head, and it carries beams at the top of a falsework or shoring tower.
Which cuplock parts does GV supply?
GV sources cuplock standards with top and bottom cups every 0.5 m, horizontal ledgers and transoms, base jacks, heavy U-head jacks and steel planks for the decks. The tube is 48.3 mm outside diameter with a 3.2 or 4.0 mm wall, sourced from qualified partners and managed for US job sites.
Which standards do scaffolding and shoring buyers specify?
US contractors typically reference OSHA 1926 Subpart L for scaffolds and Subpart P for trench shoring. GV sources each part to the size series and standard your specification requires.
How are trench struts sized?
Trench struts are sized by the width of trench they span, using the same 0 to 4 numbering as props. A size 0 strut closes to about 0.32 m and a size 3 opens to about 1.73 m, and each size adjusts with a pin and screw between its end plates.
