Scaffolding & Shoring

Temporary works have to stand firm from the day they go up to the day they come down. Corona makes the steel parts that hold them: cuplock standards and ledgers, steel planks for the working decks, base jacks and heavy U-head jacks to level and top out a tower, adjustable props with their pins, nuts and threaded tubes, and trench struts to hold an excavation open. Each part is made to the size series and standard the buyer specifies.

Scaffolding & Shoring: steel tube scaffolding with braces and working platforms on a building

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.

FacadesStair towersIndustrial plant

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.

Questions answered

Common questions about scaffolding and shoring parts.

What do prop sizes 0 to 4 mean?
Sizes 0 to 4 are the UK 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. Corona makes props, pins, nuts and threaded tubes to this series.
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 Corona make?
Corona makes 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.
Which standards do scaffolding and shoring buyers specify?
UK buyers usually name BS EN 12810 and 12811 for scaffolds and BS 4074 for props and trench struts. European buyers use EN 1065 for props and EN 12812 for falsework, Australian buyers AS/NZS 1576, and US buyers OSHA 1926. Corona makes each part to the standard the buyer specifies.
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.
