EM 8 Portable Log Siding Machines

The EM 8 Log portable seamless siding machines are robust and the profile is extremely realistic. This user-friendly machine is designed, engineered and made in the USA. The patented roll-forming profile is unique and looks great on the wall. Eastside's siding machines feature our original self-contained embossing system, which applies a natural wood grain texture to steel coil.

  • Extendable cutting table
  • Industrial hard-chrome-plated rollers
  • Chrome-plated shafts

The EM 8 Log job site roll-former is a smart add for those looking to expand within the siding industry whether purchasing or renting the portable log machine. With the maintenance concerns and upkeep of conventional real wood log siding, it is no surprise that a metal alternative is a big hit. Our patented design (patent design USD#462,790) gives the exterior look of real wood logs, made of steel. This profile looks impressive on large homes that want to look of a log cabin and fantastic in most commercial applications. It is important to be aware that this profile does require a custom foam backer that not only supports the profile, but also gives added r-value.

Portability, durability and product flexibility are just three of the many compelling reasons to choose an Eastside Machine Company built seamless siding portable roll-former. To be successful in the siding industry you need to be productive with your assets. Down time costs you money! With Eastside Machine Company's portable roll-formers, you’ll have peace of mind knowing that you bought an American-made and engineered roll-former that will make you more money. Our team is experienced and ready to help you with any questions from machine support and use to installation.

The Eastside EM 8 Log job site roll-formers are built upon a heavy-duty steel frame for structural stability and forming consistency. Industrial nitrocarburized (QPQ) steel rollers are used in all Eastside Machines. Nitrocarburizing rollers allow for improved wear, lubricity, strength and corrosion resistance. Our proprietary embossing rollers, which apply an authentic and natural wood grain texture to steel or aluminum coil, are artfully designed for pattern beauty and panel rigidity.

An extendable cutting table gives you the flexibility to make your cuts more precise. Our portable siding machines operate with a 1.5 HP 115 Volt, 20 amp electric motor and have a variable speed frequency drive. This allows our seamless siding machines an infinitely adjustable forming speed from 1 ft to 60 ft giving you the ability to do more production than other machines on the market. Our siding machines also come standard with an extendable remote switch with forward and reverse, allowing machine operation from outside the trailer.

Eastside Machine Company knows the importance of making loading and unloading coils as safe and simple as possible. With Eastside Machine Company siding machines, your installers/operators can load and unload coils without using a forklift, like most other portable siding machines. An accessory coil loading system can be mounted to your enclosed siding trailer and can effortlessly lift coils up to 2500 lbs in a matter of minutes using a 110-volt winch. Safety is very important at Eastside Machine Company and it is something we take very seriously. All our siding machines are equipped with an emergency shut-off button and a spool brake to control the coil when operating the machine.

Like all Eastside Machine Company portable siding machines, our EM 8 Log Siding machines come with operational training and technical support and a five-year warranty.

Standard Profiles & Insulation Backer

The attractive log siding profile is exclusive to the EM 8 Log job site roll-former. This unique profile was designed to give the appearance of a log cabin exterior for both residential and commercial applications. We recommend using a custom contoured foam backer engineered specifically for the EM 8 Log profile. This precisely contoured foam underlayment adds rigidity and superior impact resistance. It is available to order as needed. To learn more about the benefits and importance of the custom foam backer, call customer service at (800) 234-7834.

Guillotine Cutter

Eastside Machine offers a guillotine cutter standard on every seamless siding machine. Industrial nitrocarburized steel blade gives a very desirable, clean cut. The durability of the blade allows it to keep its sharp cutting edge, which minimizes maintenance; think of an Eastside Machine Company guillotine cutter as comparable to the Ginsu knife’s role in a kitchen.

Unidrive System
Unidrive System

Unidrive is an AC Drive and Controller system with integrated Programmable Logic Control (PLC), and comes standard on all 2016 and newer 6/8/10 Combo Siding Machines. The Unidrive converts single phase 110V to 3-phase 220V without the need of a transformer, resulting in a much more efficient use of power. Unidrive benefits include: less power used, fewer circuit breaker and GFI outlet problems and the ability to add the ATM system to your Eastside portable siding machine.

All Siding Machines come equipped with Unidrive. Benefits include: More power efficiency, fewer tripped Circuit Breaker, no transformer and the ability to add A-T-M System (Auto-Tape-Measure)

Have an older Eastside Combo Siding Machine with Softstart or Phase II Electrical? Unidrive can easily be added to 2015 and earlier models. Just call customer service at (800) 234-7834 to learn more.

Auto Tape Measure System (ATM) (Optional)

The Auto Tape Measure (ATM) system will measure the panel length as it is formed. Cut lengths can be set in the ATM without the need of measuring. Batch any number of same-length panels to increase efficiency, all while adding convenience and accuracy on the job site. ATM is also a great way to track the total number of feet used (like an odometer in a car) or the number of feet used during a single job. ATM is an upgrade that can be added to any Eastside portable siding machine with the Unidrive system. To learn more about the benefits of ATM and how it can help your install teams be safer and more efficient both in accuracy and speed, call customer service at (800) 234-7834.
