The Roll Forming Process

What advantages do roll formed parts offer, compared to other methods of manufacturing?
Roll forming is a precise, progressive bending and shaping operation that can streamline and simplify parts production. It reduces turn-around times and is compatible with close tolerance requirements roll formed parts also provide a greater strength-to-weight ratio, compared to ordinary sheet, so thinner walls can often be specified, and material costs reduced. Also, the production of rolled formed parts generates less scrap than competitive methods – a critical advantage in this era of high commodity prices.

What advantages can Rollformers offer us as a supplier of roll formed parts?Rollformers 2000 Ltd has a broad experience base manufacturing roll formed parts for the door manufacturing, construction, steel framed buildings and many other industries. We are geared to producing highly uniform products. Our lead times are generally substantially shorter than other producers of roll formed parts. And with machinery set up for jobbing work our ability to manufacture a wide range of profiles ensures our place as a truly unique NZ manufacturer.

What roll formed parts do you offer?
Simple and complex angles, Purlins, Cees, Zeds, U-channels, hat sections, C-channels, Studs, Noggins,  Ceiling battens, Roof  and Tile Battens and many other special profiles. 

What materials can be roll formed?
Roll-formed parts we manufacture include low and medium carbon steels, galvanised steel, stainless steels, and pre-painted colour steels. We also, on request, can look at materials such as aluminium, copper, bronze, and brass.

Do you offer prototyping?
Yes, we often produce rollformed parts as prototypes prior to production, and can do this on a fast track basis.

What post-manufacturing services do you provide for roll formed parts?
Hole punching, slotting and notching can be offered on request and at time of rollforming.

Metal Stamping vs Rollforming

Are there certain shapes that are more suitable to metal stampings than rollforming?
Most often, parts can be manufactured using either method. A more important consideration is quantity – when quantities are substantial, the tooling for rollforming can be amnitised over the production run and total cost for the program will be less than for metal stampings.

How does the set-up cost for metal stampings compare to rollforming?
The set-up cost for rollforming will always be less than metal stampings. And, if different parts widths are needed, the difference is very great. In this instance, metal stampings would require multiple set-ups. Rollforming different widths can be accomplished with just a simple timing adjustment.

With a long run, tool maintenance is a factor. How do metal stampings compare for this?
Tool maintenance is much less for a rollformed section than for metal stampings.

Why is this?
One major reason is that only one set of tooling is required for parts of various lengths.

How does production output compare between metal stampings and rollforming?
The pieces per hour will be higher for a roll formed part.

Can you tell the difference between metal stampings and a rollformed part strictly by appearance?
Quality rollformed parts look like metal stampings.

What about Colour Steel or plated material? Does either method accommodate this?
Rollforming and most metal stampings can be produced using pre-plated or coated material.
