Product Spotlight: HD Series FRP Grating

The HD series of fiberglass reinforced plastic (FRP) grating is design to solve one issue: vehicle traffic. Other forms of FRP grating, both molded and pultruded, are for foot traffic only. Customers frequently have the response of “well how much vehicle traffic can the other stuff take before it breaks?” The answer is it is untested. However, when it comes to FRP we are often not simply told what to quote, but to make a recommendation. And we do not recommend vehicle traffic on any FRP grating except for HD series grating.

The HD series, or “heavy duty”, is made up of thick, rectangular bearing bars and cross-rods. It is similar to the other pultruded FRP grating systems expect that it is only available in the large, thick rectangles 1″, “1.25”, 1.5″, 1.75″, 2″, 2.25″ and 2.5″ thick. This means that the product is not manufactured in an “I” or “T” shape unlike other pultruded FRP products. The grating brochure available off the Redwood Plastics website gives a full load table and specs for the HD-6000 grating. You can access the grating brochure here.

The Basic Components Of FRP

The Basic Components Of FRP

It is important to understand the materials you’re using in your application and by knowing the makeup of Redco FRP you come to appreciate the advantages it brings to the table. FRP stands for “fiberglass reinforced plastic” and for the most part FRP involves the following components: glass fibers, glass mat, synthetic surface veil, and resin. The glass fibers are probably what you think of when you think of the “glass” in fiberglass. These are bunches of long strands of glass fibers and they give impressive longitudinal strength to the end product. Wrapped over the glass fibers is glass mat, which gives strength in all directions (omnidirectional strength).

Those two components are then further bound by a synthetic surfacing veil. This veil is not in all fiberglass products available worldwide but is an important component to Redco FRP. The surfacing veil both binds the glass mat and fibers (also known as “rovings” together) providing composite strength but also importantly serves as a UV inhibitor and prevents the components underneath from “blooming” through the resin.

The final component is the resin itself which most people would know as the “plastic”. The FRP is subjected to a bath of resin which coats all the components and then is pulled through a die or set in a mold. The “general purpose” resin used is polyester; however, two other resins are used in certain applications. Vinyl ester resin is more expensive and offers the same benefits as polyester except with much better corrosion resistance and tends to last even longer in applications. This resin is most commonly used in EXTREN 625 products. The other special resin is “phenolic” and this provides fire and heat resistance not normally found with other FRP resins. Phenolic resin is especially valued by the Oil & Gas industry and can withstand fire while retaining its structural property for enough time to permit an evacuation. A good example application for phenolic resin is as FRP grating for oil drilling platforms.

Market Spotlight: Oil & Gas

There are so many FRP products available that it’s helpful to narrow down by industry and focus on a few applications. Today’s discussion is on the benefits that FRP brings to oil and gas applications. Petroleum products are extracted from a variety of harsh climates: it could be an offshore oil rig or a fracking operation in the Bakken shale. FRP operates in a wide variety of temperature ranges and is impervious to water and salt. Where other materials corrode, FRP will outlast them. In addition, the oil and gas industry values ease of installation, low weight, and durability.

It is true that metal components will have a lower upfront cost. However, they often require heavy lifting equipment, increased labor, welding, painting, and edge-banding. FRP will not require these additons to the job. This means that FRP will have a lower lifecycle cost than traditional materials such as metal. Some useful products for the oil and gas industry include FRP molded and pultruded grating, in particular DURAGRID phenolic grating, which can take high temperatures and has been successfully used on oil platforms. SAFRAIL ladders and guardrails can be substituted wherever metal ones are used. EXTREN shapes such as I-beams can be used in structures, support systems, and platforms. DURASHIELD or DURASHIELD HC wall panels function as wind walls, cladding, and for both insulated and non-insulated enclosures.

There are countless other applications where FRP can provide a durable, net zero maintenance solution allowing your business to focus on profitability. If you’re interested in learning more please contact us today.

New Product: Redco Bullnose Stair Tread

New Product: Redco Bullnose Stair Tread

Recently one of our representatives in Canada was approached with an FRP application. The customer wanted an anti-slip surface on their stairs; however, replacing the stairs with a full FRP stair solution was not possible. Instead, our rep had the idea of taking 1.5″ x 1.5″ x 1/8″ FRP angle and turning it into a solution. The angle was painted in safety yellow color and covered in a coarse grit surface and then cut-to-size. The treads were tapped and bolted on site to the existing grating with hardware procured elsewhere. This solution was much less expensive than replacing the stairs or getting them coated with another anti-slip product.

Unlike the traditional materials of metal and wood, FRP will not rot, rust, or corrode. It will provide the customer with the benefit of a near maintenance-free anti-slip solution for many years.  If you think this solution might help your business please contact us today.

Product Spotlight: Redco Utilicover

Utilicover is an underutilized FRP (fibreglass reinforced plastic) product. It is essentially a customized FRP trench covering system tailored to each customer’s individual needs but for a customized product, is remarkably easy to quote. When you approach us for pricing we will send a one page form with a diagram asking for a few simple dimensions and if the trench is a type “A” (does not buttress against a wall, IE. symmetrical) or type “B” (trench is buttressed against a wall or other obstruction and thus needs to be asymmetrical). We also need to know the length of the trench to be covered.

FRP is ideal in this application: it will not rot, rust, absorb moisture and is electrically non-conductive. It is maintenance free except for cleaning and resistant to a wide range of chemicals. In short, it provides an optimal trench cover for your application. To get started with your application contact us today.

FRP Grating As Screening

FRP Grating As Screening

 

 

 

 

 

 

When one thinks of FRP grating they think of it as flooring replacing steel walkways. However, a major application for the product is as a screen especially for large transit projects such as commuter rail projects. In this application, various forms of grating are positioned vertically just like steel or wood fencing. However, unlike those traditional materials, FRP needs far less maintenance. Steel and wood fencing will require re-painting, suffer peeling of paint, become marred with unsightly scratches, and corrode or rot. FRP when used as a fence suffers none of these problems.

On the contrary, FRP provides years of near maintenance-free use. It will not need repainting, will not peel, corrode, or rot. The only cleaning it would require is to remove physical debris from the fence: that’s it. The grating will come with UV-inhibitors so it keeps its look exposed to the outdoors. In many applications, FRP grating has been used for 25+ years outdoors without the need for replacement. All this aside, FRP is also extremely strong in regards to taking impact or load – all the better when used as a fence or screen!

For answers to your questions about Redco FRP being used as a screen please contact us.

SAFPLATE On A Grid

SAFPLATE On A Grid

Redco SAFPLATE is a versatile fiberglass reinforced plastic (FRP) product. Designed as an anti-skid multipurpose plate available with medium or coarse surfacing and is both electrically non-conductive and fire resistant. What people don’t know is that we can supply SAFPLATE bonded onto pultruded or molded FRP providing a solid, seamless surface. This is important in several applications where a raised surface is required or FRP grating is desired but the spaces in between the bearing bars serve some sort of challenge (such as dropping small objects or tripping). It opens up new solutions for FRP grating that most people probably do not even know exists.

REDCO™ SAFPLATE® is widely used for:

  • Walkways
  • Splash Walls
  • Overpasses
  • Bridge Decks
  • Pool Decks
  • Trench Covers
  • Odor Control Covers

In many of these applications a SAFPLATE and grating combination may be ideal. If you have questions or want to discuss further please contact us.

Deflection

Deflection

Deflection is one of the most important topics when it comes to FRP (fiberglass reinforced plastic) grating and it’s a topic any customer working on a new FRP application should be concerned with. Deflection refers to a level of “bounce” FRP grating has when a load gets placed on it. Problems really start to occur when the load is dynamic, IE. someone walking on the grating where their weight is being applied and removed. At a certain point the deflection becomes so severe that it makes walking on the grating dangerous as you could fall. The way around deflection is to reduce the span, IE. the distance between supports. The closer the supports are together, the less deflection there will be.

What is handy is that our brochure available here gives some tables of reference for the safety factor and deflection for a variety of grating profiles at various spans. This would serve as a good start as you consider your application. It is said that deflection, not strength, governs the designs of FRP grating projects and for the most part this is true. If you have further questions about deflection or how it might affect your application please contact Redwood Plastics.

 

Quoting FRP Ladders

Quoting FRP Ladders

Custom FRP (fiberglass reinforced plastic) ladders are a common inquiry we receive. The ladders replace metal ladders and last longer because they are corrosion-resistant. They are also light, easy to install, and available in specialty grades such as NSF 61 certified for potable water contact. While some parts of the ladder are standard and the “blanks” can be filled in by us on a quote request, there is still some critical information we need from you, the customer.

The main piece of information that is often missing in a ladder request is to do with a cage. Firstly, we need to know if you even want a cage but we also need to know if you want the standard “walk-thru” or side mounted cage. We also need to know if we can floor mount the ladder or can wall mount only. Any special certifications that are required, such as being NSF 61 safe, need to told to us upfront. Options such as custom color or painting of the ladder and knowing if we’re required to provide a freight charge should be discussed up front.

When it comes to the process of ordering a ladder that can sometimes seem unclear. Every FRP ladder contract will require a drawing to be approved first prior to production of the ladder. This drawing must be signed and faxed or emailed back to us. It takes up to 2 weeks to get the drawings and once approved, a further 3-4 weeks to manufacture the ladder. This means a total lead time of 4-5 weeks from purchase date to shipment.

For a quotation on a FRP ladder or to answer questions you may have please contact us.

EXTREN Panels vs. FRP Wall Panels

Posted by on Mar 17, 2017 in Redco™ EXTREN® | 0 comments

EXTREN Panels vs. FRP Wall Panels

One area our customers get confused sometimes is that we offer two types of FRP (fiberglass reinforced plastic) panels. Also, as the FRP wall panels are a “commodity” plastic the public would encounter in everyday life, they may think they are the EXTREN panels. But lets look at the key differences between the products.

FRP wall panels are primarily white “pebble embossed” panels meant for areas like food processing plants and gas station bathrooms. The panels are durable and easy to clean. They come in 4′ x 8′ or 4′ x 10′ sheets with a standard thickness of 0.090″. They are FDA and CFIA approved for indirect food contact. EXTREN FRP panels; however, are not meant for food-safe applications but are otherwise more versatile. They’re much thicker, starting at 0.125″, and available in all three EXTREN resin types. They can be used in structural applications such as flooring. The panels can also come in virtually any size up to 5′ x 10′. The key difference is the variety of the EXTREN panels in thickness of 1/8″-1″ and 4′ x 8′ or 5′ x 8′ panels. The EXTREN panels are higher quality and more expensive but are not meant for the same applications.

If you have questions about the types of Redco FRP paneling available please contact us.

(NOTE: Redwood Plastics can only sell FRP wall panels within Canadian borders).
