Structural Steel Tubes
Rejected tube which cannot be classified as a prime product because of some
physical or chemical defect is sold by the mills to steel tube distributors,
distributors of steel products, fabricators, and consumers. These tube is available
in CW, ERW, DSAW and seamless, in all sizes, weights, and classes of material.
Although reject tube carries no warranty whatsoever, it can have application
for structural purpose.
Few of the typical examples where reject tube has been used as structural steel
tubing and tubes are handrails, columns, posts, piling, sand-wash, casing, culverts,
fence, caissons, sign poles, bumpers, bracing, parking meter posts, towers,
supports, rollers, etc. Structural steel tubes and tubing are normally priced
substantially under prime tube and can affect large savings in the right application.
Steel Fencing
Owing to its high tensile strength, steel fencing is extensively used as architectural
and landscape furnishings at many industrial, commercial and recreational sites
around the world. Fence fabricated from steel, are robotically welded, then
hot-dip galvanized and polyester powder coated. This makes various fencing components,
such as mesh, bolts, hooks and gates, extremely durable. This process afford
maximum durability with minimal compromising of surface smoothness. Matching
liquid paint is provided for final touch-up.
Architects and landscape architects have used steel fencing to design a variety
of shelters, lighting standards and decorative sculptures for street-scapes,
parks, bus and light rail stops, shopping centers, malls, sports stadiums, office
buildings, parking lots and other facilities. Steel fence are carefully designed
with clean lines, structural integrity and ease of installation. These fences
are available in variety of heights and widths in multiple configurations.
Steel Handrails
Hand rails made from steel has gained worldwide acclaim, as it provides excellent
resistance against corrosion and weathering. While manufacturing, steel handrails
are subjected to close scrutiny in terms of design details, finishes, and authenticity.
Steel handrails last for years and their upkeep is minimal. Stainless steel
handrails are generally wall mounted and come with adaptable fittings that enable
it to be installed without special measuring. It is easily installed at any
location and can be produced to meet any conditions.
The use of steel handrails is both varied and functional. They are used for
protection, crowd control and often just for visual and ornamental effects.
Used widely in office blocks, shopping & town centres, swimming pools and
leisure centres, these handrails are available in various sizes, styles and
colors to fit any application. The colors and finishes available assure the
possibility of matching or contrasting with individual color choices. Steel
handrails can also be used throughout the home to provide safety and help prevent
falls along hallways, steps and ramps.
Steel Columns
A vertical element , a column is that part of a structure whose purpose is to
compress the weight of the structure. Steel columns have seen an increased usage
in building structures throughout the world. Derived from a multi-step manufacturing
process, steel columns are used to distribute loads over a supporting pier,
wall or foundation, while constructing commercial or residential buildings.
Steel provide high temperature stability, highly inert deactivated inner surface
and exceptional mechanical durability to the columns.
Steel columns are being increasingly used for structural applications, due to
its aesthetic appearance, high corrosion resistance, ease of maintenance and
ease of construction. They are perfect for field use or high vibration situations,
as these columns cannot break. These heavily loaded columns are used in multi-storey
buildings to support beams or arches and in the design of other civil engineering
structures, which employ composite design techniques.
Steel Stove tubes
Heavy-duty steel stove tube is designed for use in the residential and commercial
coal & wood burning units, and is intended for interior use only. In many
industrial, as well as public and domestic applications, the stove tubes are
exposed to elevated temperatures. Steel stove tube is preferred due to its high
creep strength and ductility, with high resistance to oxidation and HT corrosion
and good resistance to erosion-corrosion.
Apart from gas & some oil applications, steel stove tube is popularly designed
to connect a wood stove to a nearby chimney, and is available in different thicknesses.
It is usually painted with a high temperature black paint and some manufacturers
produce steel stovetube in porcelain enamel colors to match their stoves. The
welded seams of these tubes assure the tubes roundness, making installation
a very easy task. Steel stove tubes is much lighter and is not prone to rust
over time.
Steel Exhaust tubes
Exhaust tube is a general term for several different tubes used throughout the
exhaust system. The configuration of exhaust tubes made of standard or stainless
steel vary with different makes, models and engines. The steel exhaust tube
is made of either aluminized steel, stainless steel or zinc plated heavy-guage
steel. These tubes route exhaust gas away from the engine, through the catalytic
converter and muffler and out the rear of the vehicle. As a result, pollution
and sound are reduced, while ensuring safety by directing exhaust gas away from
the vehicle.
Exhaust gas, especially carbon monoxide, can be deadly if it enters the interior
of the car. The sturdy properties of steel prevents an exhaust leak. The diameter
and length of steel tube are engineered to provide proper exhaust flow, silencing,
and emission levels on a particular engine. Steel exhaust tube provide lifetime
warranty, beautiful extruded seamless design with rolled edges and is corrosion
proof.
Steel Chimney tubes
The purpose of a chimney tube is to take the combustion products, ie, smoke
and gases from the appliance to the atmosphere outside the home, and at the
same time, to draw air for combustion into the appliance. Steel chimney tubes
have become a popular, low-cost alternative to conventional brick chimney. Steel
chimney tubes are made by different manufacturers, but all meet the same basic
design standards. They begin with two steel cylinders, one inside the other.
Then they pack the gap with insulation. In almost every case, the insulation
is made of ground-up fiberglass plus silica.
Rigid or flexible, steel chimney tubes always come in some type of insulation
around it. The steel provides a continuous, even lining, and the insulation
forms an additional layer of protection. Steel is preferred over other material
because of its acid and heat resistant qualities. Steel also has uniform material
strength throughout the entire structure providing more consistent and predictable
results than wood. Steel chimney tubes are constructed properly, structurally
sound and can be properly installed.
Steel Poles
The unique attributes of steel give engineers ultimate flexibility in poles
that meet load requirements and all industry standards. Steel pole are hot-dip
galvanized for maximum protection against corrosion and can also be color coated.
These are stronger, more durable and environmentally friendlier than competing
wood structures. In addition to being recyclable, another one of the environmental
advantages of steel poles is that they are impervious to insects and rot. Therefore,
unlike traditional wooden poles, steel poles do not need toxic chemical preservative
treatments and do not create future hazardous waste disposal concerns.
Poles are fabricated with uniform dimensions from steel, providing superior
strength, consistent performance, and enhanced reliability. Steel poles also
have the flexibility to be designed as per the requirement and can be engineered
to meet any specific loading criteria. They are lighter in weight and easier
to install, require less maintenance and offer lower overall life cycle cost.
Steel poles can be custom designed and fabricated to support larger and heavier
loadings with longer spans as well as being able to meet greater height requirements.
