Slide Bearing Longevity: Teflon® vs. Fluorogold®

Posted on Wed, Aug 27, 2014 @ 10:59 AM

Note: PTFE is the generic name for what people often refer to as Teflon®. Genuine Teflon® is a registered trademark of the DuPont Corporation. Most of the slide bearing assemblies that The Steel Supply Company provides are made with Fluorogold®, which is a PTFE and Fiberglass composite. Fluorogold® is a registered trademark of the Saint-Gobain Corporation.

Hot Dip Galvanizing: Threaded Steel, Anchor Bolts, Turnbuckle Rods & Threaded Studs

Posted on Mon, Jul 28, 2014 @ 11:20 AM

For most fabricated structural and miscellaneous steel, hot dip galvanizing is a fairly basic process. The galvanizers follow the applicable specification, usually ASTM A123 / A123M, or the corresponding AASTHO spec. As most steel members or finished assemblies are stationary, excess zinc is not a problem.

Vent Hole Plugs: Aluminum vs. Zinc

Posted on Thu, Jul 24, 2014 @ 09:16 AM

Here's a quick note regarding Vent Hole Plugs. The large majority of customer requests are for aluminum Vent Hole Plugs. However, they are also available in zinc. There are several reasons a fabricator will request zinc rather than the less expensive and more malleable aluminum. The foremost reason would be potential corrosion. Mind you, we would be talking about corrosion over a very long period, possibly 20 to 30 years... but some jobs will call for the plug to be zinc.
