Structural Beams / Heavy Duty Profile Sections | Dura Composites
Saved by uncleflo on February 12th, 2022.
The proven versatility of d2 Dura Profile makes it a logical and cost-effective alternative to carbon, steel, aluminium, wood or other conventional materials. We carry one of the largest stock holdings of GRP profiles in the country including Angle, Channel, Box and Tube sections, all of which are designed to meet or exceed the higher performance E23 grade requirement of the BS EN 13706 standard (which covers the specification of GRP pultruded profiles). Dura Profile structural profiles also offer unrivalled strength to weight, non-conductive, noncorrosive and chemically resistant and fire-resistant properties. The standard profile range we stock are produced in 6m lengths in ISO resin and in dark grey RAL 7043. Dura Profiles can also be produced in other resin systems and sizes as a special order, subject to minimum order quantities. d2 Dura Profile provides the engineer with a high degree of design freedom and offers exceptional material properties for a wide range of applications. The profiles shown below can be cut to specific sizes by our fabrication team. Please speak to a Dura Composites sales representative on +44 (0)1255 446838 to discuss your requirements.

Electropolishing - Wikipedia
Saved by uncleflo on April 3rd, 2021.
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating. It may be used in lieu of abrasive fine polishing in microstructural preparation. Typically, the work-piece is immersed in a temperature-controlled bath of electrolyte and serves as the anode; it is connected to the positive terminal of a DC power supply, the negative terminal being attached to the cathode. A current passes from the anode, where metal on the surface is oxidised and dissolved in the electrolyte, to the cathode. At the cathode, a reduction reaction occurs, which normally produces hydrogen. Electrolytes used for electropolishing are most often concentrated acid solutions having a high viscosity, such as mixtures of sulfuric acid and phosphoric acid. Other electropolishing electrolytes reported in the literature include mixtures of perchloric acid with acetic anhydride (which has caused fatal explosions), and methanolic solutions of sulfuric acid.
