Sawing

Linders Specialty Company maintains a pair of Marvel vertical tilting head band saws with a clamping capacity of 18” by 18” and a feed length of 18”. Beyond the standard use for these saws we have measured their tables and travel paths and programmed them into our CAD system. This allows us to create trimming fixtures to not only precisely trim parts by attaching the fixtures directly to the saws but in ensures consistency by providing a check fixture for every part coming out of our rollers and benders. We can also create compound miter cuts quickly and accurately with a special fixture designed to bolt directly to the saws’ tables.

Roll Bending

Linders Specialty Company has the largest variety of rolling machines in Minnesota and west of Milwaukee. We can roll bend sections from as light as formed sheet metal to one hundred pounds-per-foot beams. We have been in the rolling business since 1975 when we started with a Pullmax Z-23 angle roller capable of rolling 3x3x3/8 angles. Since then we have added both larger and smaller machines to better serve our customers’ needs.

Our extensive experience has allowed us to design our own tooling for standard structural sections, pipe, and tubing as well as specialty rollers for rail cap, custom formed parts and aluminum extrusions.

Our commitment to quality has never wavered and we continuously strive to maintain the highest accuracy standards through the use of check fixtures and innovative measuring equipment designed specifically for roll bent parts.

If your design requirements include any non-stock shapes contact Linders Specialty Company for design assistance.

Angle Rolling

Linders Specialty Company has machinery capable of roll bending angle in any size available as mill rolled stock.

2 x 2 x 3/16 A36 Angle, Leg Out, untrimmed
4 x 4 x 1/4 A36 Angle, Leg Out, Trimmed
2 ½ x 2 ½ x ¼ A36 Angle, Leg in

Bar Rolling

Linders Specialty Company has the capacity to roll bend flat bars the hard way up to 10” wide and 2” thick. We can also bend bars and the easy way as well as provide welded rings.

3/8 x 2 ½ 304 Stainless Flat Bar, Hard Way, Trimmed and Welded
¾ x 4 A36 Flat Bar, Easy Way, Trimmed
½ x 3 6061 Aluminum Flat Bar, Easy Way with Tangents

Beam Rolling

Linders Specialty Company has the capacity to roll bend wide flange and structural beams the easy way up to one hundred pounds per foot. Our specialty is accurately rolling trolley beams with curved corners and tangents attached reducing splicing in the field or the shop to provide our customers with a drop-in product. We can leave ends untrimmed if field conditions preclude accurate measurements.

We can roll structural beams (S beams) the hard way if they are the heavy sections and under 6” in section. These are usually large enough for most conveying sections.

We can also split beams into Tees, roll the tees separately and weld them back together to get tighter bends than would otherwise be possible in one piece. Special machinery is required to roll the hard way beyond this. We do not possess this capability at this time.

W12 @ 22 lbs/ft, Easy Way

Channel Rolling

Linders Specialty Company has the ability to roll bend mill rolled channels in any size offered either legs in or legs out. We can roll channels the hard way in all bar sizes and up to ten inches in milled rolled sizes. When rolling the larger size channels, we stitch weld the toes together to form a box section and plasma split them apart after rolling. Special machinery is required to roll the hard way beyond this. We do not possess this capability at this time.

1 x ½ x 3/16 Bar Sized Channel, Hard Way
C6 @ 8.2 lbs/ft, Legs In, Trimmed
MC12 @ 10.6 lbs/ft, Leg Out

Pipe and Round Tube Rolling

Linders Specialty Company has tooling for many commonly available sizes of pipe and round tubing. We can roll single radius parts as well as combined radius parts such as elliptical sections, coils and spiral hand rails. We have developed mathematical calculations that allow us to layout and bend spiral and curved stair rails quickly and accurately. Provide us with the plan diameter, degree and direction of turn and total rise of your stair and we will produce your pipe and round tube rails.

8 x 2 x ¼ 6061 Aluminum Tube, Easy Way
8 x 3 x 5/16 A513 Tube, Hard Way
2 ½ x 2 ½ x 5/16 A513 Tube
6 x 6 x 3/8 A513 Tube
2 x 2 x ¼ A513 Tube to 24” Inside Diameter

Square and Rectangular Tube Rolling

Linders Specialty Company is tooled up to bend a wide variety of square and rectangular tube sections. We have designed our tooling to support the corners of the tubes to reduce deformation during the roll bending process allowing tighter roll radii.

1 ¼” Schedule 40 A53 Pipe, 6 Bends on 5” CLR
1 ¼” Schedule 40 6061 Aluminum Pipe, Pushed Rolled, 2 bends
2 3/8 OD x .154 Wall A500 Tube, Push Rolled, 6 Bends on 12” CLR
1 ¼ Schedule 10 304 SS Pipe, Pre-polished, 5” CLR over Mandrel

Manual Tube Bending

Linders Specialty Company uses our Ercolina electric manual rotary tube and pipe bender to produce your parts economically. The setup is quick and repeatable, accurate parts are easy to achieve and short run economy is easily achievable.

We can bend your hand rails, pipe ladders and other parts to eliminate welding and grinding elbows saving enormous costs and shortening lead times dramatically while providing better looking parts.

We can bend pipe and tube to match your samples such as high-pressure hydraulic piping for quick turn-around in the event of a failure or plant shut-down repairs.
