Scaffolding & Shuttering Material

ARENA - CUPLOCK SYSTEM
The backbone of “ARENA” scaffolding arrangements is our cuplock system. Its unique qualities of being fastest, economic, versatile and safe make its use universal and irresistible. It is fabricated out of requisite grade virgin steel i.e 40 NB ‘B-Class’ ERW steel tubes. The connection point is set at 500/1000 mm intervals. To handle the hazards of rough site handling malleable cast iron is used to cast out mobile captive cups and the bottom cups are of high quality virgin H.R sheets duly welded to MS steel tubes. Loose or welded joints pins are provided for strong and hassle free bonding between vertical (standard) members. These verticals are then joined with identical fit in horizontal members having forged end ledger blades to slide into the cups of the verticals.

ARENA - CUPLOCK VERTICALS / STANDARDS
“ARENA” verticals comes in a wide range of sizes e.g 3.00, 2.50, 2.00, 1.50 , 1.00 and 0.500 mtrs. apart from any specific size to keep in the requirement of the clients. These verticals are fabricated out of 40 NB ‘B-Class’ ERW steel tubes and have connection points at fixed interval of 500 mm. The top end has an optional inner or outer socket welded to the vertical for joining the two verticals.

ARENA - ADJUSTABLE TELESCOPIC PROP
The important aspect of construction of beams, slabs, wall and columns are sported by adjustable telescopic prop. It is an inevitable, most suitable and yet user friendly part of shuttering system. Its fabrication is done out of B-Class steel tubes and is in two parts i.e prop outer and prop inner. The outer is fabricated out of 50 NB ‘B-Class’ ERW steel tubes having threaded/slotted top end, a malleable C.I nit with handle for finer adjustment, the bottom is provided with welded 150 x 150 x 6 mm MS flat base plate. The prop inner is fabricated out of 40 NB ‘B-Class’ ERW steel tubes having holes at a regular interval of 150 mm. The Top end is provided with welded U/Flat or beam head.

ARENA - ADJUSTABLE TELESCOPIC SPANS.
These spans are fabricated out of 2 or 2.5mm sheet as Body members, lattices of 10 mm round bars, main bar of 14 or 16 mm T-Section of 40 X 5mm. These spans have unique qualities of extreme safety and negligible supervision. They do not require any intermediate support. The load carrying capacity, size and their respective openings are tabulated as under :

ARENA - H FRAME SYSTEM
Rectangular welded frames are fabricated with 2 Nos. of Verticals and 2 Nos. Horizontal members out of 40 NB ‘B-Class’ ERW Steel Tubes. To meet the requirement of height, the top end of vertical members are provided with welded inner / outer sockets to join 2 frames vertically. Horizontally these frames are provided with scissor type cross braces. 50 NB ‘B-Class’ ERW Steel Tubes are used in H Frames to withstand heavier structures as well as for the heightened constructions. Sizes available are : 2000 x 1250mm, 1500 x 1250mm, 1250 x 1250mm, 1000 x 1250mm, 900 x 1250mm.
