Since the discovery of steel modern man has had the ability to create with unlimited potential. The creation of modern machinery to manufacture and produce a wide range of metal formed products such as guardrails and highway beams, steel stud and zee purlins have enabled companies to manufacture high quality products.
Many of today’s roads or driveways intersect a highway near to the end of a bridge or other immovable, restrictive features of the highway. To protect and shield both the end of the bridge and the embankment, a strong post W-beam guardrail curved around the corner is used. The manufacturing of these interstate or highway guardrails is typically done best with a roll former. Roll forming equipment is used to bend and ‘form’ the various grooves and profiles in to a flat metal roll. Compared to other forms of metal bending such as brake pressing or stamping roll forming is much more cost effective and produces a higher quality product. It should be noted that the terms ‘roll forming’, ‘rollformer’, ‘cold roll forming’ and ‘metal roll forming’ are all interchangeable. When selecting a roll forming company as with any other capital equipment purchase pricing is typically a less important part of the equation.
As with many other large capital pieces of equipment roll forming machines can be manufactured from very cheap to very expensive. So how do you know which is the right guardrail roll forming machine for you? Well, keep in mid several key factors.
1) How long has the roll forming company been in business?
2) Is the roll forming machine built for long term reliability?
3) Are the roll forming stands built to handle repeated bending of metal?
4) Will the profiles been the same day after day year after year?
5) Does the roll forming company use FEA (finite element analysis) when designing roll tooling?
6) Is the roll forming company ISO certified?
These are some important questions to ask yourself before you choose a roll forming manufacturer. Another area that is very important is how much money will you spend on re-work scrapped or return product? Often with cheap inexpensive roll forming machines from China you will have to factor in the cost of poor quality parts. This cost can amount to a lot of money over a short period of time. It is usually better to start with a quality roll forming machine such as the Samco Machinery roll former. With in a short period of time you will see how cost is no longer the only factor to use when purchasing a roll former. Quality, durability and long term re-work costs are some of the key issues to consider.
Many quality companies use the Samco Machinery (http://www.samco-machinery.com) roll formers when they produce steel formed products. The output is always of a higher quality and the cost per unit production is lower then less costly poor output machines.
