Outrigger Pads: How To Spec Pad Size

Most of the time selecting a size of Redco outrigger pads isn’t rocket science: you get pads with the same length x width that came with your equipment. However, when for whatever reason this is not possible, there is some simple math you can do to figure out a safe outrigger pad size*. You first need to know the softest type of ground you may put your pads on. In general, 20-22 PSI (virgin soil) works well. Next, you need to take a look at a decal that should be on your outrigger pad feet. It should say a maximum force that foot could put on the ground.

Finally, you need to know the area of the outrigger pad you want to place your outriggers on. Here are the most common measurements:

18″ x 18′ = 324″

24″ x 24″ =576″

36″ x 36″ = 1296″

42″ x 42″ = 1764″

48″ x 48″ = 2304″

Let us work through one example. Assume the decal on your outrigger foot reads 30,000 pounds as it’s maximum force that could be applied. Let us consider the 24″ x 24″ pads, the math goes like this: 30000 / 576 = 52.08

52.08 is the PSI is the pressure at max load the foot would be putting on the ground through the pad. This is too much force for virgin soil, so we must go larger. We then consider 48″ x 48″ pads:

30000 / 2304 = 13.02

Much better! 13.02 is far below the 20-22 PSI we’re looking for and should be a safe amount of load to put on the ground in most situations. And it’s always better to be safe than sorry with a crib.

Anti-Slip Matting And Tiles

Redco anti-slip matting and tiles are a versatile and easy-to-install solution for slippery areas. The tiles are made of tough, wear-resistant plastic and are made of 100% recycled materials. In fact, the system is a “closed loop” wherein recycled tiles are made into the new product. The tiles are not degraded by heat, cold or sun exposure and come in a variety of colors and with or without grit surfacing. The tiles are resistant to most chemicals and fungicide. They are also manufactured with an interlocking system on all four sides to connect with each other or sloped plastic edging which is available to make your tiles into an eyewash station, for example.

The most common tile profile, commonly referred to as the “standard” is 12″ x 12″ x 3/4″ thick but tiles are also available 12″ x 24″ and 36″ x 36″ and in 1/4″ and 1/2″ thicknesses. Common applications for the tiles include anti-slip walkways besides pools, industrial facilities, wet food processing areas, showers, locker rooms, ramps, the only limits are a sturdy substrate and your imagination.

BRAXX Anti-Slip Surfacing

After decades research and design, several “anti-slip” plastic options are now available and BRAXX should not get lost in the shuffle. BRAXX is a standardized UHMW based anti-slip plastic which comes in 36″ x 108″ sheets that are 0.30″ thick. The material comes in two forms “BRAXX Sand” which has a base color of blue dotted, with a sand-impregnated surface and “BRAXX Luns” which has a high-visibility safety yellow colored base and is dotted with LUNS clean coal slag anti-slip grit. BRAXX serves as a heavy-duty replacement for anti-slip tapes and paints. Both types of BRAXX are comparable in price and effectiveness, it comes down to personal preference for color and grit.

Applications for the two materials have few limitations. At 0.30″ thick, BRAXX is non-load bearing and is meant to be placed on top of another surface, typically flooring, stairs, etc. As the plastic is UHMW nothing sticks to it and mechanical fixation is required: you will not to bolt or screw into the substrate. Advantages of BRAXX are that it will not rot, rust, absorb moisture, or otherwise corrode. It is impact resistant and easy-to-install on top of other substrates such as wood, aluminum, or steel. Originally developed for the U.S. military, BRAXX is now available to the general public.

Nylon For Specialty Applications

Nylon is a family of plastics with several different additives that make them suitable for applications where natural-grade nylon isn’t optimal or won’t be successful. There are three grades of nylon specifically that should be highlighted for their properties in applications with unique demands.

Firstly Redco SL which offers a low coefficient of friction with excellent wear resistance. It was developed for applications where external lubrication is either very difficult or impossible. Redco SL performs better than other nylons and many plastic where the part is rarely accessed for maintenance.

Secondly, Redco glass-filled nylon serves very well for prototypes. The glass filling results in a very dimensionally stable part which can be held to tighter tolerances. This part also has the lowest “cold flow” of any nylon. If you’re looking for a “proof of concept” part than Redco glass filled nylon is an excellent choice.

Lastly, Redco blue is a grade of nylon for high-heat applications, able to withstand up to 250 degrees Fahrenheit ongoing in application. This alone isn’t especially unique, as several plastics such as PTFE handle temperatures just as high. However, Redco blue nylon is the best “bang for your buck” for a heat-tolerant plastic. The alternatives such as the aforementioned PTFE, PEEK, ULTEM, etc. are all much more expensive. If you’re having trouble finding a heat-tolerant plastic and you know your application is 250 degrees F or less, then Redco blue may be an excellent choice for your application.

Coffee, Baseball, And Polycarbonate

Today we’re highlighting a recent application by our Spokane branch. Recently we were contacted by Dutch Bros. Coffee who has a location at Avista Stadium: home of the Spokane Indians baseball team. Dutch was looking for a clear plastic to protect their storefront signs and graphics. General-purpose polycarbonate was chosen for its excellent impact strength which will prevent breakage from anything from vandalism to accidental bumps. In addition, the polycarbonate is much more forgiving with drilling than acrylic – and several screws were tapped into the sheet. The polycarbonate was 3/16″ thick for this application. The picture below shows the completed application.

The #1 Myth About FRP Wall Panel

FRP wall panels are used everywhere: from gas stations, to food processing facilities, to mud rooms at home. Customers are curious about the accessories, colors, and installation methods but one “speed bump” usually comes up that gives the project a pause. Customers who are looking into an FRP wall panel project tend to request smooth panels because they believe the smooth panels will maintain a cleaner, longer lasting, vandalism-resistant surface. This is a myth!

In reality, the textured FRP panels are superior. They are designed so that dirt, grime, mud, liquids, marker, etc cannot imprint. The smooth panels, while they might look a bit more attractive for the first few months, will eventually become permanently stained or defaced. The smooth surface allows filth, marker, biological waste and other contaminants to stick and gather on the surface. The textured panels on the other hand were specifically designed to resist all these contaminants. The pearly, asymmetrical surface compels grime and liquids to drain off or at least bead for easy cleaning. The bumpy surface doesn’t allow for vandalism such as graffiti as those liquid-based contaminants will also bead.

There is no catch. As the textured surface was designed to be the new ‘standard’ in FRP wall panels it is more available, and less expensive, than the smooth panels. While there are many variables to consider in your FRP wall panel project, do not waste time or money on smooth panels unless this is absolutely necessary (and you know the consequences!).

Product Spotlight: Redco ULTEM

High performance plastics face extra challenges other materials do not. Because of the prevalence of consumer grade plastic, unfortunately plastic with much of the public has become synonymous with “cheap” – low price and low quality. Unfortunately, this is a complete myth for the three grades of plastics (engineering/industrial, high performance, and imidized) that are above consumer grade plastics. In fact, at the higher tiers of quality plastics widely outperform metal and other traditional materials in most applications. And this does come with a subsequent increase in product cost (though usually a lower “lifecycle cost”). But for your money you get quality in a phenomenal material.

ULTEM (polyetherimide – “PEI”) in its virgin form has an interesting amber/translucent color. It handles hot water and air well, up to 332 Fahrenheit in continuous operation. Its resistance to repeated steam sterilization makes it a prized material for medical tools and devices. ULTEM is also very useful to the electronics industry due to its dielectric constant and arc resistance. It is also resistant to gamma radiation and does not absorb water. ULTEM is considered a dimensionally stable plastic with high strength and rigidity allowing it to be machined precisely to tighter tolerances than other plastics would allow. It is also available in 10, 20, and 30% glass filled grades to offer even higher dimensional stability.

If you have a high heat application requiring a precisely machined part ULTEM may be the optimal plastic for you. To discuss this or other plastics please contact us.
