design experience.
Engineering has always been a major strength of the company. The engineering disciplines provided by Roeslein are
mechanical, electrical, instrumentation & controls and structural. Roeslein has professional engineers on its staff that
are registered in many states throughout the U.S. and has also developed strategic alliances with outside engineering
firms and contract engineers to provide even more breadth of service.
Roeslein’s concept-to-completion philosophy means that its engineers and design documents are generated with
construction, plant operations and maintenance in mind. Roeslein Engineers typically follow the project through
construction bidding to the actual construction and start-up, minimizing conflict that traditionally exists between
engineering and construction contractors.

5. Roeslein’s unique approach to the construction process is a high-
performance, integrated solution proven to deliver reduced start-up times,
improved efficiency and reliability, and quicker system deployment and
return on invested capital.
The modularized, unitized, and preassembled methodology applied at
our fabrication facilities in the US and China consolidates our control
over interdependent and often unpredictable factors during fabrication,
construction, and installation. By foreseeing and controlling these factors,
and their costs, we are able to:
• Deploy a more qualified labor force
• Maximize product quality
• Reduce project schedule
• Improve overall project safety records
• Execute a more efficient, aggressive installation and start-up timeline
• Realize cost savings for our customers

MODULAR
FABRICATION
Steel Fabrication is accomplished
through the strict adherence to American
Welding Society (AWS) Structural Welding
Code D1.1. Our welders operate advanced
equipment, employing the latest welding
techniques and safety practices. In order to
ensure our proprietary unit sections are 100%
accurate, they are assembled in a computer-
designed jig to specification.
Pipe Fabrication will always meet or
exceed our customers’ expectations through
continual in-house training and in-house
Certified Welding Instructor classes. We
follow the ASME Section IX requirements in
our segregated stainless and carbon shops,
our Welding Program incorporates Welding
Procedure Specifications (WPS), Procedure
Qualification Records, (PQR) and Welder
Performance Qualifications (WPQ).
Paint systems adhere to each customer’s
required specification. Keeping abreast of
the latest technologies, we incorporate the
use of a high-temperature, high-pressure,
environmentally safe chemical spray system
to prepare our “clean” steel for our paint
application systems. We also have the
in-house capability to meet any of the Steel
Structures Painting Council’s (SSPC) surface
preparation requirements.
Electrical work encompasses all needs
associated within the electrical field.
Your preassembled process systems will
incorporate power/control cabling and/or
wiring run in conduit, cable, or ladder tray with
the complete integration of power panels,
control cabinets, lighting, and operator control
stations. We have the capability to not only
provide system testing and checkout, but also
to optimize line control programming.
Modularization has many proven
advantages: reduction of on-site construction
time and personnel; reduced labor costs;
fabrication in a controlled environment;
increased safety, quality, and efficiency;
simultaneous and parallel project scheduling;
as well as many other benefits leading up to
reduced overall project costs. Unitizing is our
unique and proprietary concept of utilizing
structural, free-standing, prefabricated and
painted or galvanized unit sections to provide
low-cost, common mounting structures for
comprehensive mechanical and electrical
systems as well as equipment and access
walkways with handrails.
Preassembled Systems combine the
advantages of modularization and unitizing by
integrating the completed process modules,
unit sections, and interconnecting pipe
spools, plus electrical and support systems
into their finished form at our facility. We
then test and/or run the completed systems,
and then after passing our quality control
measures, we partially disassemble them into
large piece-marked and bar-coded sections
to be transported via truck, rail, barge, and/or
overseas container to the final installation site.
Roeslein Modular Fabrication in Red Bud, IL features 375,000 sqft
of fabrication space situated on 17 acres.

Roeslein Asia follow the product to the field to perform the final installation. This methodology allows us to deliver the
highest-quality product on schedule and within budget.
When needed, Roeslein augments our in-house resources with additional subcontractor partners. During our 25
years of construction experience we have developed a database of highly skilled craftsmen. These trusted partners
encompass all areas of civil, mechanical, structural steel, and electrical construction. They become part of our project
team as necessary and expand our capabilities.
Roeslein recognizes that every project has unique specifications and requirements. We have the qualified workforce
and experienced leadership to tailor our processes to complement our customers’ philosophies and expectations.
