Fiberglass Tanks in Bethlehem, PA

Fiberglass tanks anchor corrosion-resistant storage across Bethlehem, and as established fiberglass tank manufacturers Design Plastic Systems builds vessels engineered for durability and efficiency in the Lehigh Valley's industrial base. Water treatment, chemical processing, and food manufacturing operations rely on FRP storage that meets strict safety and performance standards and holds up where metal would corrode. Resin selection drives long-term performance, with vinyl ester for harsher chemistry, isophthalic for general duty, and specialty resins for the most aggressive applications, and FDA-compliant systems are available where food contact requires them. Filament winding produces consistent bulk storage vessels, while contact molding handles the irregular custom geometries that plant retrofits and tight-clearance installations demand, all certified to ANSI B 31.3. Captor double-wall construction protects sensitive storage for facilities near the Lehigh River drainage. Tanks ship with manways, vents, level connections, and tie-down details integrated rather than added later, built to match each operation's volume and chemistry. We also supply polyethylene storage tanks as an alternative to FRP where the chemistry allows, in vertical, horizontal, cone-bottom, and double-wall forms. Chemical storage tanks, plastic tanks for wastewater treatment, and food-grade process vessels all come out of the same operation, with help choosing the right materials and the documentation that keeps a project on schedule. Whether the requirement is a single day tank or a multi-vessel build, the engineering conversation starts with what is going in it, how aggressive, how hot, and for how long, with field-installed builds handling vessels too large to ship as a finished assembly.

Fiberglass Pipe Repair in Bethlehem, PA

When a process or treatment line fails in a Bethlehem facility, fiberglass pipe repair restores it without the cost and downtime of full replacement. A corroded run, a cracked fitting, or a failed joint can interrupt a chemical process, a food-manufacturing line, or municipal utilities, so the repair has to be both fast and correct. Design Plastic Systems backs Bethlehem facility and maintenance teams with repair products, on-site guidance, and the technical support to match each fix to the original pipe's chemistry and pressure class. Stop It® pipe repair tape and wrap systems handle emergency containment on the spot, holding a line until a permanent repair can be scheduled between outages. For structural repairs, we supply the resins, laminates, and fittings to rebuild damaged sections to specification rather than patching them temporarily. Our plastic systems engineering team works the failure with your crew to determine whether the cause is chemical attack, mechanical damage, or thermal cycling, then recommends a repair that addresses the root cause. Because much Lehigh Valley work sits near the Lehigh River, containing a release fast is as important as restoring the line. Twenty-four-hour emergency response covers the failures that industrial and municipal operations cannot afford to wait on. The objective on every Bethlehem repair is to get the system back online safely and keep it there.

Fiberglass Pipe in Bethlehem, PA

For Bethlehem facilities that need industrial piping resistant to corrosion, pressure, and extreme temperatures, fiberglass pipe is a smart solution that performs where steel or standard plastic degrades. As a distributor of fiberglass plastic pipe systems for industrial use since 1981, Design Plastic Systems matches corrosion-resistant plastic systems to the fluid, temperature, and pressure conditions each Bethlehem installation actually runs. Lightweight and easy to install, the pipe is highly resistant to chemicals, which makes it ideal for wastewater, chemicals, and industrial fluids across the Lehigh Valley's manufacturing and processing base. We offer a range of diameters, resins, and pressure ratings to meet specific performance requirements, and our team ensures each system is compatible with existing infrastructure and adheres to relevant engineering standards. Whether you are expanding a plant or replacing aging pipelines, we deliver fiberglass pipe built to last, and every order ships with the material certifications industrial and municipal procurement require.

Fiberglass Grating in Bethlehem, PA

Fiberglass grating is an excellent choice for Bethlehem facilities seeking strong, slip-resistant flooring and platform solutions, commonly used in walkways, platforms, trenches, and rooftop applications thanks to its lightweight structure and low maintenance needs. Design Plastic Systems offers both molded and pultruded fiberglass grating designed to handle a range of industrial conditions. Molded grating is produced in a single bidirectional pour that interlocks the bearing bars, giving strong corrosion resistance, good impact tolerance, and balanced strength in both directions, which suits walkways, platforms, and trench covers around process equipment. Pultruded grating is formed by pulling continuous glass roving through resin and a die, producing a high-strength unidirectional profile that carries heavier loads over longer spans with minimal deflection. Unlike traditional steel, fiberglass grating will not rust or deteriorate in damp or corrosive environments. We provide options in multiple resin types, sizes, and surface textures to match your facility's safety and structural requirements, and we can create custom grated structures including stairs complete with handrails. Both grating types come with gritted tops for slip resistance in wet areas, and we also supply the fiberglass structural shapes and stair systems that complete a platform package. Panels are cut and fabricated to each project's dimensions, reducing field labor and waste. From a single trench cover to a full rooftop platform, the grating is matched to the actual service environment rather than pulled from one-size stock.

Thermoplastic Piping and Valves in Bethlehem, PA

Thermoplastic piping systems give Bethlehem's water treatment, chemical processing, and food manufacturing facilities a corrosion-resistant alternative to metal for chemical, process water, and high-purity service. Material selection follows chemistry and temperature: PVC and CPVC carry general chemical and process water service, polypropylene steps in where temperatures and concentrations push past CPVC limits, and PVDF covers high-purity and aggressive chemistry. HDPE plastic systems serve underground utilities, fire mains, and the larger process runs around Lehigh Valley industrial and treatment sites. We pair every system with valves from Georg-Fischer, Asahi/America, Hayward, and PureFlex, and supply the fusion technology and double containment that ship standard for any line where a leak would create a regulatory or safety event. Custom plastic fabrication runs through our shop for prefab spools, manifolds, and skids built to drawings, with field crews handling on-site installation when work needs to be built in place.

The thermoplastic piping systems and valve products we supply for Bethlehem include:

• PVC/CPVC Piping
• Polypropylene/PVDF Piping
• Secondary Containment
• Fusion Technology
• Double Containment
• HDPE Pipe
• PVC/CPVC Pipe Fittings
