Pre painted galvalume steel

What is Pre painted galvalume steel?

Pre-painted galvalume steel is manufactured by colour coating galvalume treated steel substrate. The typical composition of galvalume coating is 55% aluminium, 43.4% zinc and 1.6% trace elements. Galvalume coated steel is usually produced in a continuous galvalume line. They are then applied with various layers of organic coatings which can be paints, vinyl, or laminates. Pre painted galvalume steel has superior long term corrosion resistance in most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminium.

Excellent corrosion resistance and lower heat conductivity make Pre-painted galvalume steel, the preferred choice for roofing and cladding applications. They find their usage in a myriad of constructional purposes like Pre Engineered Buildings, Rain Ware, Landscaping, and Recreational Centres. They are also widely accepted in construction of white good appliances & automotive body parts.

Let us see what make Pre painted galvalume steel an ideal choice for use in an array of applications:

Better corrosion resistance: Superior resistance to corrosion means longer service life for buildings, appliances etc.

Heat reflectivity: Pre painted galvalume steel doesn’t allow too much conduction of heat and ensure a safe and cool environment within the building.

HFIW

What are HFIW steel tubes

HFIW (High Frequency Induction Welding) tubes are manufactured by cold forming of steel coil into desired shape followed by welding using high frequency induced current. A high frequency coil develops current into the tube ahead of the squeeze rolls. The edges are pushed together between squeeze rolls to produce a joint of welding. The welding of the edges forms a small bead inside and outside the tube. These beads are then scarfed from the tube to give a smooth surface finish. Surface heating by induced current and the squeezing action by rollers are the two main principles behind production of high frequency induction welded steel tubes.

HFIW steel tubes do not need any filler material. This makes the process very fast and highly efficient in production. High frequency induction welding allows us to produce variety of shapes of tube with an almost invisible weld joint that is stronger than the parent material and are suitable for critical applications. The ability to manufacture a high quality and critical welded product, offers architects a flexible solution to design the perfect profile shape for their end application. HFIW is commonly used in manufacturing structural steel tube, transportation & mechanical tubes.

Let’s take a look at the benefits of HFIW process to manufacture steel tube:

1) High Efficiency: High frequency induction welding is an efficient welding process to manufacture tubes as it consumes less electricity than other welding processes.

2) Able to weld very thin walled tube: HFIW is suitable for steel tube with a wall thickness as low as 0.15 mm.

3) High welding speed: High-Frequency allows high welding speeds up to few hundred m/min.

4) Produces welds with very narrow heat affected zones: HFIW process is capable of producing focused heat thereby protecting the work piece from damage. The focused heat produces very narrow heat affected zones near weld bead.

5) Superior weld quality: It provides stronger & uniform weld seams which make the steel tube suitable material for structural applications.

6) Easier cleaning processes afterwards: Induction welding offers cleaner work pieces once they’ve been welded than other welding processes.

7) Highly automated: Most of the steps in the HFIW process can be performed automatically which makes the operation streamlined & time-saving.

How does the use of structural steel help in creating the greener environment around us

Structural steel is a fast, safe and efficient building material. It comes off as the best material for construction owing to its various features like high strength, fire resistance, flexibility, long lasting, offsite manufacturing, reusability and recyclability. These characteristics of structural steel result in many social, economic and environmental benefits to satisfy sustainability’s ‘triple bottom line’.

Here’s what makes structural steel an environment friendly building material:

  1. Structural steels don’t decay or decompose: Steel structures mature with age, rather than deteriorate and decay. The longevity of a building is indispensable to its sustainability. Steel frame do not require any type of special treatments to prevent mold, decay or insect infestation. Steel cannot absorb moisture and therefore cannot host any bacteria that would compromise the health of the home’s habitants.
  2. Reusability of structural steel: Steel structures are intrinsically reusable. Steel-framed buildings can be dismantled, and reused. Any steel which cannot be reused is recycled for further use in construction. Designers & Architects can take responsibility for sustainability by efficient deconstruction of steel building. Research shows that 99% of structural steels are reused or recycled.
  3. Steel is endlessly recyclable: Structural steel can be recycled indefinitely. This referred as multicycling. The multicycling of steel lessens the environmental issues. Over 500 million tonnes of steel are multicycled worldwide each year and that’s a whopping amount. Because of its unmatched magnetic property, it’s easy to remove from waste land. This makes steel the most recycled building material in the world.
  4. Offsite construction: Steel construction is carried out by small group of skilled workers in a accordant manner which is safe and predictable. Reduced time at site means lower costs, quicker returns and fewer disruptions to the local community. Structural steel is manufactured in a factory controlled environment and delivered at site when needed.
  5. Reduces overall energy cost: With advancement in engineering & technology, the energy required to produce raw steel has dropped by 60% since 1960. Off-gases from the furnaces can be totally reused. Electric arc furnaces allow steel production from scrap metal. Producing steel from scrap requires much less energy than producing new steel.
  6. Protect humans & environment: Steel releases no harsh chemicals or toxins and can easily be retrieved from the environment with magnets. It’s not harmful to the humans as well as the environment. Steel is also resistant to natural calamities such as flood, snowstorms, and earthquakes. Use of structural steel also reduces pollution as compared to other building methodology.
