Equipment Highlight: 500 Ton Press Brake

Posted on: May 29th, 2016 by Jazzy Elliott

What is a press brake and how does it work?

At PTL we have lots of specialized equipment, and our team of experienced technicians is ready to use each piece. One of these is our 500 Ton Press Brake. A press brake or brake press, is a machining tool used to bend sheet metal. It forms bends by clamping the sheet of metal that needs to be bent between a punching side of the machine that is aligned with a die side.

The machines are made of two C-frames which form the sides of the press brake. These are connected to a fixed table at the bottom and a movable beam at the top. The bottom tool is mounted on the table with the top tool mounted on the upper beam.

There are several types of brakes, they are named for the way that force is applied to create a bend:

With technology improving quickly for hydraulics and computer controls, computer controlled hydraulic machines have quickly become the most popular type of brake press used today.

Press brakes often include multi-axis computer-controlled back gauges. Optical sensors allow operators to make adjustments during the bending process. These sensors send real-time data about the bending angle in the bend cycle to machine controls that adjust the parameters. This helps to make for a more exact bend, which is essential to modern building and fabrication techniques.

To learn more about our 500 ton press brake and more of our specialized equipment, contact us at PTL. At PTL we employ experienced millwrights, riggers, ironworkers, welders, pipe fitters, pipe welders, and more armed with a complete arsenal of specialized equipment. PTL can provide crews from 1 to 80, ready to take on any job. Let us get to work on your project today!

PEMB: Pre-Engineered Metal Building

Posted on: April 27th, 2016 by Jazzy Elliott 1 Comment

A pre-engineered building is the perfect choice for a wide range of structural and aesthetic design choices.

Pre-engineered Metal Buildings are typically known as buildings that are all metal but that isn’t always the case. The major difference between the metal building and the other systems is the way the system is designed and the nature of the components. The design of the PEMB is processed through complex software that analyzes each of the various members at all locations along the lengths of those members.


Historically, the primary framing structure of a pre-engineered building is an assembly of I-shaped members. A computer is used to design the beams for these building. They are designed to meet the required maximum load at each point along the length of the beam. This is why you see tapered beams and columns in a metal building. This is one of the reasons that metal buildings are less expensive than other types of buildings. The I beams are then assembled to form the entire frame of the pre-engineered building. Once the frame is in place our teams will use a variety of materials (dependent on each project) to create the outer walls, roofing, and interiors. Some of these materials include:

Advances in computer-aided design technology, materials, and manufacturing have helped grow the amount of styles available when you are designing and customizing a PEMB to your exact needs


When designing a pre-engineered building, engineers consider the clear span between bearing points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection criteria, internal crane system, maximum practical size, and weight of fabricated members. Once all of these factors have been determined and input, the designers will then select the most efficient I beams size for their projects based on the computer’s recommendations.

Energy Efficiency

Because buildings account for such a significant amount of the energy consumed in the world, choosing materials and designs with sustainability benefits provides one of the biggest opportunities to be environmentally conscious. There are a wide variety of insulation systems that significantly improve the performance of the roof insulation. Also, an efficiently designed pre-engineered building can be lighter than conventional steel buildings by up to 30%. Lighter weight means less steel, and a potential price savings.

At PTL we offer a variety of services that include installing PEMB, as well as complimentary construction and fabricating services. To learn more about your options when building a PEMB, contact us today. At PTL our reputation for customer satisfaction and quality, as well as competitive pricing, and experience makes us a trusted source for businesses of all sizes.

Do you know what a baghouse is?

Posted on: January 14th, 2016 by Jazzy Elliott

At PTL we are skilled at industrial ventilation.

This includes ducts and baghouse installations. So, what exactly is a baghouse? The simple way people sometimes explain them is by referring to a baghouse as a “giant vacuum”. Although this summary is correct in principle, a baghouse is so much more. With a baghouse, a system can be engineered for almost any dust producing application, covering almost any set of circumstances. This places them into a totally different class than a giant vacuum.

A baghouse is an air pollution control device that removes particulates out of air or gas released from commercial processes or combustion for electricity generation. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants. Baghouses came into widespread use in the late 1970s after the invention of high-temperature fabrics capable of withstanding temperatures over 350 °F.

Baghouses can…
