Robco Wiper Blocks For Hot Galvanizing Wire Lines

Longer Life / Better Surface Finish

Robco’s High Temperature Division supplies high performance wiper blocks for the galvanizing wire industry to maximize operation efficiency. We develop superior, longer lasting wiper blocks to support and improve productivity by reducing scrap rate and downtime.

Achieving longer wiper block life and superior wire surface finish is our ultimate goal. Let us help you do just that!

Robco 4260 The workhorse

High abrasion resistance, yet soft on wire surface, #4260 is our standard block for general purpose wiping. The wiping area is made of 100% high quality para-aramid filaments treated with high temperature resistant lubricants. Available in Regular or High-Density (HD) hardness.  Cross-Section: 1/2” to 1-1/4” Length: 1” to 72”

Robco 4260HD Softer and malleable

Similar to Robco 4260HD, our Robco 4260 Regular is softer and ore malleable, because of the addition of a much higher incorporation of PTFE additive. A good choice for the production of larger wire requiring more deformable wipers, where the wiping table cannot accommodate wider and larger wiper blocks. Cross-Section: 1/2” to 1-1/2” Length: 1” to 72”

Robco 4290/4292/4295 The soft ones

Using high quality para-aramid spun yarn, instead of standard laments, our #4290 series wiper blocks deform easier and accommodate larger wires. They can also be coated with a graphite-based compound to help dissipate surface heat.   Cross-Section: 1/2” to 1-1/4” Length: 1” to 72”

Robco rolled para-aramid blocks The classic

Made of para-aramid fabric saturated with rubber and surface treated with a high temperature lubricant, our rolled blocks are the product of choice with applications that require larger blocks.  Cross-Section: 1/2” to 2” Length: Any

Robco thin wiping pads

Lowering cost of material used Thinner is better! These thin pads made from lubricated high-quality para-aramid fabric, are used in conjunction with regular blocks, simply to lower the initial acquisition cost.  Width: 3/4” to 2” Length: 1” to 72” Thickness: 1/4” to 1/2”

Robco pre-formed para-aramid blocks Improved homogeneous wiping

These blocks are vulcanized into a pre-moulded form, to wipe more evenly on bigger wires and avoid high pressure points on the wire. Made from para-aramid fabric saturated with rubber and treated on the surface with a high temperature lubricant.  Cross-Section: 1” to 2” Length: 1” to 18”
