Metal Sheet Piles
Sheet Piles are by definition, structural units which when connected one to another, will form a continuous wall, generally for retaining earth or excluding water. Individual pieces or pre-interlocked pairs are installed by driving them into the earth using impact hammers, vibrators or by water jetting. In functioning as a wall, the sheet piling acts as a beam under load and therefore requires the capability to resist bending. In certain applications, ability to resist bending is not important but strength of interlock is.
Sheet Piling is manufactured in three basic configurations "Z", "U", and "Straight". They can be formed either "Hot Rolled" or "Cold Rolled". A recent development to the industry is the production of some sheet piling shapes by the cold-forming process in which hot rolled sheet is fabricated into traditional sheet piling shapes. These new additions to product availability contain interlocks which are considerably different from the hot-rolled product. Manufactured from a hot-rolled coil of sheet, it is slowly fed through a series of rollers which gradually bends or forms the steel into its designated shape. Sheet Piles manufactured through cold forming process attain better physical properties and dimensional tolerances than compared to that manufactured by hot process. Apart from the advantage of higher section modulus, moment of inertia and sectional area per meter of wall there is advantage of 20% weight as well.
Application of Cold Formed Sheet Piles:
Construction of docks and ports
Waterways
Breakwater
Protection of river banks and channels
Protection of construction pits in soil and water
Bridge embankments
Retaining walls
Foundations
Underground parking
Underpasses, ramps and tunnels
Slope protection
Environmental protection and rubbish dumps
Noise barriers
Enclosure of contaminated soils
Civil and industrial sites
Civil defense
Military engineering
Metal Crash Barrier
Metal Crash barriers are basically Road safety system. It works like hard shoulder which prevents vehicles from colliding with obstacles such as boulders, walls, buildings and also prevents vehicles entering into large storm
drains, steep slopes or deep water. Hambro Tech introduces Metal Crash Barriers of different thickness/gauges depending upon the requirement.
Applications
• As restraining barriers on embankments of Expressways & Highways.
• As containment barriers on medians and grade separators of four/six lane roads.
• As protection barriers/containment barriers for hilly terrains and ghat roads.
• As racecar crash guards on car racing tracks.
• For interior traffic safety at Airports, Plants handling hazardous chemicals, mines, collieries, etc.,
• As fencing barriers for country border lines, expanse lands, water bodies, bridge piers, signposts, rocky areas etc.,
Z and C Section Purlins-
Purlin function as a form of support for rafters and are horizontal structural members in a building, architecture or structural engineering. They are used to increase roof spans without the need for increasing rafter sizes or compromising wall stability.
Roof Sheet
We are the reputed manufacturers of a wide range of Roofing Sheet that are designed and manufactured as per the latest technological advancements. Manufactured using superior quality materials, these sheets are available in different standard sizes and thicknesses. Tested on various quality parameters, the sheets are appreciated for environment friendliness, low maintenance and optimum performance.
The technical specifications of the range is as follows:
PMS profile is 1080 mm wide coverage with 28-30 mm deep ribs at 200-250 mm center to center with two/three stiffners in between ribs.
Weights are based on cover width for bmt as shown. Substrate is galvalume steel (150 gms / m2 coating mass) & galvanised steel in 120 gsm/m2 coating mass.
Properties of profile are calculated in acordance with is-801. Section properties take into account reduced width of compression flange in accordance with is-801
