Preassembly of well bay platform of Glass-Steel plant.
Above: Fiberglass circular troughs with fiberglass weirs, scum baffles, and mounting brackets were installed in three 140’ diameter clarifiers at the Laredo, TX Municipal Treatment Plant.
Above: Four preassembled platform systems ranging in size from 3’ wide x 21’ long x 9’ high to 11 1/2” wide x 58’ long x 9 1/2” high were installed in the chlorine manufacturing area at Dow Chemical in Freeport, TX.
This circular platform surrounds an air stack at a major chemical plant and provides access for EPA workers to take air samples of emissions.
Grating with well holes are added to preassembly.
This 10’ x 250’ operating aisle platform is on of four such structures prefabricated by Glass-Steel and shipped to a $3.6 billion petrochemical project in Saudi Arabia.
Glass-Steel ladders meet the requirements of OSHA 1910.27. For more information on OSHA requirements regarding ladders and laddercages contact Glass-Steel.
Note to Specifiers - Typical details and other information needed to specify Glass-Steel handrail systems or ladders are available from Glass-Steel.
Examples of fiberglass structures and systems for offshore use include the following:
Final assembly of platform in progress on Southpass 62.
Glass-Steel walkway and platform systems are designed to be strong, durable and easily installed at the work site. When size permits, systems are fabricated and shipped preassembled to the customer. Typical environments include chemical, wastewater treatment, offshore, electrical, and plating operations. In many cases Glass-Steel fiberglass platforms cost less than equivalent steel platforms on an initial cost as-installed basis. Additional cost savings are realized through the elimination of maintenance costs over the life of the platform.
The Glass-Steel walkway and platform systems meet the requirements of OSHA Standard 1910.23 for handrail and 1910.24 for stairways. For more information on OSHA requirements regarding platform stairways systems contact Glass-Steel.
Glass-Steel fiberglass ladders and laddercages are in use today in a variety of severe environments. Typical applications include:
The chemicals present in water/wastewater plants are often largely unknown; therefore, Glass-Steel fiberglass structures are ideal for these operations because EXTREN is impervious to a wide range of chemicals. Glass-Steel products for water/wastewater are described below.

The use of fiberglass structures on offshore drilling rigs and production platforms is rapidly expanding. Benefits of fiberglass include resistance to saltwater corrosion and significant weight reduction. For existing platforms where congestion is typical, structures of high-strength fiberglass are much easier to retrofit because of the relative light weight of fiberglass (80% less than steel). An additional benefit of fiberglass is the elimination of cutting torches and or welding to make field modifications thereby saving the cost of shutting the wells in.
extren Fiberglass Structural Shapes
EXTREN fiberglass structural shapes are available in over 100 standard sizes and shapes. EXTREN is produced in three series designed for different environments and applications.
EXTREN 500 An all-purpose line utilizing a polyester resin system.
EXTREN 525 An all-purpose line utilizing a fire retardant polyester resin system.
EXTREN 625 A premium line of fiber glass structural shapes - both fire retardant and highly
corrosion resistant, utilizing a vinyl ester resin system.
All EXTREN Shapes have a surfacing veil to protect against “fiberblooming”, increase corrosion resistance, and aid in UV resistance.
The following features of EXTREN which are readily translated into user benefits are shared by fiberglass gratings used in Glass-Steel fabrications.
Additional information on EXTREN, including a product brochure with properties data, a corrosion resistance guide, and a size availability list, is available from Glass-Steel.
The Glass-Steel handrail systems meet the requirements of OSHA standard 1910.23. For more information on OSHA requirements regarding handrails and guardrails contact Glass-Steel.
Glass-Steel is experienced in the design of fiberglass structures and systems and is ready to design structures for you or assist you in your design. Glass-Steel’s extensive experience in fabrication procedures, joint design, and stress analysis of composite assemblies coupled with the use of MMFG EXTREN results in fiberglass structures of superior, cost-effective design and structural integrity.
Design and analysis at Glass-Steel is supplemented by physical testing to ASTM standards in MMFG’s Bristol, Virginia laboratory. Lab testing is used on each lot of material to assure published minimum values are met. In special circumstances actual loads may be simulated in the lab to verify designs.
Detailing is an extension of the engineering function at Glass-Steel. Clear, straightforward drawings are completed and the necessary approvals obtained before fabrication begins. Field assembly drawings are provided as necessary

Customers rely on Glass-Steel fiberglass cabletray because it will not deteriorate from chemical attack or weathering, is non-conductive, nonmagnetic has a low coefficient of thermal expansion, excellent dimensional stability, is lightweight and requires no maintenance. Glass-Steel tray is manufactured in four load sizes (25, 50, 75 & 100 pounds per linear foot). All standard Glass-Steel cabletray is manufactured to a 2:1 safety factor. All fittings are shipped fully assembled, including FRP splice plates. Custom cabletray can be designed and built to meet any loading requirement or special condition.
Glass-Steel cabletray installations are founding chemical processing plants, petrochemical operations, water and wastewater treatment facilities and on offshore platforms.
Glass-Steel cabletray meets the requirements of NEMA Standard FG1. For more information on NEMA requirements regarding cabletray contact Glass-Steel.
