HOW FIBER REINFORCED POLYMER (FRP) COMPARES
to Traditional Materials
LIGHTWEIGHT
Strongwell FRP weighs up to 75% less than steel and 30% less than aluminum – ideal when weight and performance counts.
CORROSION RESISTANT
Strongwell FRP is unaffected by moisture or immersion in water when sealed. Will not rust like metal and will not rot like wood.
LOW MAINTENANCE
Strongwell FRP is durable and impact resistant. It will not dent or deform like metals. Resists rot and corrostion, eliminating the need for constant maintenance.
SIMPLE FAB & INSTALL
FRP costs on average 20% less than steel to install with less down time, less, equipment, and less specialized labor.

Stairtreads and Covers
Strongwell offers a variety of stair treads and stair tread covers to meet the specific requirements of your application. Treads can be molded or pultruded in multiple colors and configurations.
SAFRAIL™ Industrial Railing System
SAFRAIL™ industrial fiberglass handrails are commercial railing systems for stair rails, platform/walkway handrails and guardrails.
DURAGRATE® Molded Grating
Light weight, high strength, resistance to corrosion, and ease of fabrication on site make DURAGRATE® ideal for a variety of applications such as walkways, equipment screening, and sunshades (as seen above).
SAFRAIL™ Ladders & Cages
SAFRAIL™ fiberglass ladders and ladder cages mounted on the sides of tanks and buildings are a common sight in a wide range of industries. Fiberglass ladder and ladder cage systems have been in use since the 1950’s in chemical plants and other corrosive environments. Even in complete immersion applications, fiberglass has outlasted aluminum and steel and required little or no maintenance.
SAFPLANK® Interlocking Decking System
SAFPLANK® is a versatile system that interlocks for a continuous smooth surface. SAFPLANK® can be installed horizontally for decking and sunshades or vertically for windwalls.
COMPOSOLITE® Structural Building Panels
COMPOSOLITE® Structural Building Panel system can be used in various roofing and cladding applications. The example above utilizes this system for windwalls.
Custom Pultrusions
Strongwell’s expertise in pultrusion design, engineering and manufacturing makes it possible to offer unique solutions to meet customers’ exact requirements. In-house drafting, FEA Analysis and 3D modeling capabilities, as well as an in-house engineering staff, provide key advantages when seeking to manufacture custom pultrusions.
Fabrication
In addition to its manufacturing capabilities, Strongwell offers full-scale fabrication of all of its products, from simple cut-to-length operations to full scale pre-assembly of its full line of products.
CASE STUDIES
from the Offshore Market

Composites Aid Next Generation Subsea Rock Installation Vessel
COMPOSOLITE® was outfitted throughout the mobile pipe tower due to its weight savings, particularly important in the lowering of the vessel’s center of gravity. This is crucial, as the vessel can also transform into two additional rock installation functions known as the fall pipe launch via side and tremie pipe distribution. Both of these require a slight shift of the tower to gain closer proximity access to offshore structures.
Durability Study: Decades Later: Still Better than New Steel
In 1979, over 10,000 square feet of DURAGRID® I-4000 1″ (formerly DURADEK®) pultruded grating was installed in lieu of steel grating in the well bays and adjacent areas on Shell’s offshore platform Ellen. The platform was destined for the Beta Field off the shore of southern California. Now, with over 40 years of use, the grating continues to show an excellent return on investment for current operators, Beta Offshore.
