We are manufacturing and exporting Hollow Sections, Hollow Steel Sections and Hollow Section Tubes
as per customer's requirement with anti rust oil coating from inside & outside of the tubes to
ensure safe delivery to end customers.
|
We have developed our core competence in the manufacturing and supplying of high quality hollow
sections that are engineered according to the specifications of our clients. Product innovation and
quality control has helped us meet the ever expanding demands of the industry.
|
The use of steel tubular sections provides for strong, light and profitable structures and as a
result offer a host of possibilities in terms of application (expressive capacity). The use of these
products also facilitates designs with a greater aesthetic appeal.

Applications
- Furniture industries
- Domestic applications
- bus body
- fencing etc.
|
Their main advantages are as follows :
Design
- Lighter and more diaphanous structures. Pieces of greater length with fewer joints.
- Large spans. More transparent trusses and purlins with the possibility of eliminating
transversal bracing.
- More slender supports. Fewer sections, which can be reduced even more with the use of
tubular sections filled with concrete.
- Economical solution. Easily executed direct joints, shorter construction times and easy
maintenance, are the results of a correct design and the guarantee of a competitive delivery
date and price.
- Expressive capacity. Circular, square, rectangular and elliptical sections, a range of wall
thicknesses for every dimension of tubular section, absence of sharp edges,etc. These are the
elements that provide innovating, wide ranging possibilities for architects and engineers.
Strength
- Compression - For the same centered compression load and under the same conditions tubular
sections allow for the use of longer elements than possible should open sections be used. If
pillars are involved, a concrete fill permits to reduce further the amount of sections used.
- Torsion - Their stiffness is the highest of all commercial steel sections. For this reason,
their behaviour is unbeatable in the case of lateral bulging or warpage.
- Bending - Due to the distribution of material on two axes, their behaviour in bending in two
directions, is close to that of a beam and better than that of open sections.
- Tensile - The use of welded joints throughout their extension means that the resistant
section in the joints is used completely, unlike bolted joints or those with gusset plates.
- Fatigue - The wide range of mechanical applications in which we can find steel tubular
sections are eloquent proof of their perfect behaviour in these conditions.
- Fluid-dynamic - Their low opposition to the thrust of fluids allows lighter sections to be
used and makes them the perfect element in outdoor or underwater structures, such as posts,
masts, towers, cranes, etc.
Safety
Protecting steel tubular sections by means of surface coating is easier and more
economical than open sections due to the absence of cavities and the lower surface area to be
covered.
Passive protection:
Structures made from Tubular Sections offer higher fire resistance than open
sections due to a lower surface area exposed to fire in relation to mass(lower form factor/mass).
Mixed structures based on tubular sections filled with concrete, show excellent behaviour in the
presence of fire because of a delay due to the higher thermal inertia.
Active protection:
Filled with water, or when water flows through them due to the thermalsiphon
effect, irrigated structures provide almost unlimited fire resistance. Maintenance of water
circulation, with the replacement of any losses that might occur due to vaporisation, ensures that
the structure is cooled in such a way that gradually the temperature stabilizes at values not very
much higher than the water status change temperature and very much lower, therefore, than the
critical temperature of steel.
In addition to:
- Introducing longer elements in structures.
- Reducing the number of joints.
- Eliminating struts.
- Stiffeners and plate brackets, to reduce weight.
- A concrete fill increases the surface area per floor.
- Their shape facilitates maintenance and represents an economic solution.
