panel profiles
There are many different kinds of portable roof panel rollforming machines to choose from, and each can make various types and styles of metal roof panel profiles. What’s the difference between snap-lock and fastener flange? Do you know which portable rollforming machines make specific profiles?

At New Tech Machinery (NTM), we know that there’s so much more that goes into your decision to get a portable roof panel machine than just the features of the machine itself. It’s important to know which profiles are available for the machine you’re considering and understand which materials to use for that panel profile.

In this article, we’ll discuss the differences between different standing seam profile styles, what panel profiles we offer at New Tech Machinery, and which portable roof panel machines make each profile.

If you’re unfamiliar with metal roofing or rollforming terms, check out our comprehensive Metal Roofing & Rollforming Glossary with definitions of words used often in these industries.

 

Types of Metal Roof Panel Profiles

Standing seam metal roofs are a type of concealed fastener metal panel system with vertical legs and a flat area between the legs. It’s a popular option for both metal roof and wall systems as the fasteners in this metal roof design aren’t visible and, as such, are protected from exposure to weather and the elements.

There are a variety of different panel profile styles, including:

  • Snap-lock

  • Mechanical Seam

  • Fastener Flange

Other metal roofing profiles that may be available with your portable rollformer include:

  • Flush Wall and Soffit

  • Proprietary profiles specific to a certain manufacturer/distributor

For this article, we’ll only discuss the types of panel profiles available with New Tech Machinery roof panel machines.


Metal Roofing Rollforming Glossary

Snap-lock Panel Profiles

snap-lock panel profile
Snap-lock panels are rollformed into shape with a male and female leg which snap together without utilizing a hand or mechanical seamer during installation. They are typically used on roof slopes of 3:12 or greater unless otherwise specified by the manufacturer. 

They are typically cheaper, faster, and require less labor to install.  Once the seam is engaged, the panel is installed. You also don’t need to rent or purchase any seaming tools. Snap-lock profiles are a common choice for both commercial and residential building applications.

New Tech Machinery’s portable roof panel machines can manufacture a variety of snap-lock profiles, including:

 

SS450

Panel seam: 1 1/2” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” on SSQII, 12” to 19 7/8” on SSH, and 11” to 15 7/8” on SSR

Machines that make this profile: SSQ II™ MultiPro Roof Panel Machine (SSQ II), SSH™ MultiPro Roof Panel Machine (SSH) *currently discontinued, and SSR™ MultiPro Jr. Roof Panel Machine (SSR)

 

SS450SL

Panel seam: 1 1/2” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” on SSQII, 12” to 19 5/8” on SSH, and 11” to 15 5/8” on SSR

Machines that make this profile: SSQ II, SSH, and SSR

*Please note: the same roller set can produce either the SS450 or SS450SL profile; one just needs an extra roller to convert an SS450 profile to the SS450SL profile.

 

SSQ550

Panel seam: 1 1/2” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” 

Machine that makes this profile: SSQ II

 

SSQ675

Panel seam: 1 3/4” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24”

Machine that makes this profile: SSQ II

Both the SSQ550 and SSQ675 are also structural profiles capable of spanning open purlins, depending on the material you use and the finished panel’s width. Be sure to check what engineering is available for max purlin spacing.

 

Mechanical Seam Panel Profiles

mechanically seamed profiles
Rollforming machines also make mechanical seam profiles, although this type of panel profile has vertical legs that line up together. Then, a hand or mechanical seamer seams the panel legs, connecting the panels. 

Mechanical seamed panels are typically stronger than snap-locks. However, the fact that they require seaming tools can make them more labor-intensive and costly to install. Some potential problems can come with using this type of profile, such as the seamer may jump and damage the seam.

One significant benefit of using mechanically seamed panels is that you can use them at a lower slope than snap-lock panels. Mechanically seamed panels are a great option if the roof slope is 2:12 or less unless otherwise dictated by the project specifications or panel design limitations.

NTM mechanical seam profiles include:

 

SS100

Panel seam: 1” high 

Panel material: Painted steel, painted aluminum, copper 

Panel coverage: 12” to 24” for SSQ, 12” to 21” for SSH, and 12” to 17” for SSR

Machines that make this profile: SSQ II, SSH, and SSR

 

SS150

Panel seam: 1 1/2” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” for SSQ, 12” to 20” for SSH, and 11” to 16” for SSR

Machines that make this profile: SSQ II, SSH, and SSR

 

SSQ200

Panel seam: 2” high

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12 to 24” 

Machine that makes this profile: SSQ II

 

SSQ210A

Panel seam: 2” high 

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12 to 24” 

Machine that makes this profile: SSQ II

 

*Both SSQ200 and SSQ210A profiles are made with the same roller set; one just needs an extra roller to convert from SSQ200 to SSQ210A. 

The SSQ200 and SSQ210A are also structural profiles capable of spanning open purlins, depending on the material you use and the finished panel’s width. Be sure to check what engineering is available for max purlin spacing.

 

Fastener Flange Panel Profiles

fastener flange profiles
Fastener flange profiles have similar characteristics to snap-lock profiles, except they are directly fastened to the roof deck through a flange on the panel’s male leg. Once fastened, the female leg snaps over the male leg. Because the fastener’s head is the only thing keeping the panels attached to the roof deck, it is not as strong as other snap-lock profiles that utilize clips to affix the panel to the roof deck.

This panel profile is typically used for higher slope applications, popular on residential buildings, and a cheaper standing seam profile option because you don’t need as many accessories to install them. They also don’t need clips for installation, saving time and money. It is recommended to run shorter lengths of panels when installing them due to oil canning or distortion from changing temperatures or expansion/contraction of metal.

Fastener flange profiles don’t always have engineered testing available, so they may not qualify for weathertight warranties. You’ll also need a substrate or decking on the roof to put the metal panels over.

At New Tech Machinery, we have these fastener flange profiles available:

 

FF100

Panel seam: 1” high

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” for SSQ, 12” to 20” on SSH, and 11” to 16” on SSR

Machines that make this profile: SSQ II, SSH, and SSR

*Clip relief rollers are recommended with this profile to prevent potential fastener head distortion.

 

FF150

Panel seam: 1 1/2” high

Panel material: Painted steel, painted aluminum, copper

Panel coverage: 12” to 24” for SSQ, 12” to 18 11/16” on SSH, and 10” to 14 11/16” on SSR

Machines that make this profile: SSQ II, SSH, and SSR

*Clip relief rollers are recommended with this profile to prevent potential fastener head distortion.

flush wall and soffit profiles
We have flush wall/soffit/underdecking panel profiles available with the SSQII Roof Panel Machine. As the name suggests, this panel profile’s seam lies flush with the wall instead of having legs as in other standing-seam profiles and is used as an architectural wall panel, soffit panel (with the optional perforations, you can have a vented soffit), or underdecking panel. It also offers an adjustable reveal from 0 to 3-inch increments.

Panel seam: FWQ100 is 1” high, FWQ150 is 1 1/2” high
