    PAINTING OVER GALVANIZING

    We are developing noise-attenuated panels with 16 ga, G90 galvd, sheet steel skins that will become sound proof envelops for power generating equipment. They can expect to be in service 30 years, and be used in any U.S. location. At some future time we cannot control, the owners may field...

    WEATHER TIGHT STRUCTURAL RIVETS

    We are building sound insulated panels from commercial quality 16 ga G90 galvanized sheet steel formed into panels. The design requires a spine beam made continuous with the panel skin. Our preferred method is pop riveting. Does anyone know a rivet system that is: - weather and leak tight on...

    GALVANIZED STEEL CONTACTING CONCRETE

    Currently, we are having our fabricators mask the underside of baseplates before galvanizing our columns in order to prevent any reaction between the zinc and the grout. Since we erect quite a number of columns, this is an expensive approach. Can anyone advise: - is it advisable/compulsory...

    ALUMINUM/STAINLESS STEEL INTERFACE

    We need to secure a flange made from 6061 Aluminum angle with 1/2 dia Grade 316 stainless steel bolts. The flange offers a flat surface exposed to weather with a 30 year service life in a mildly corrosive industrial environment. The nut and washer face into the weather. Can anyone advise us...

    TAPPED BOLT HOLES IN ALUMINUM

    We need to connect the skirtings for 30" bus ducts to the wall of the isophase box. Details as follows: Wall is 1/2" thick in 6061 aluminum. Bolt groups are 24 - 3/8" dia on 18" radius. Design load achieved 20 times in life. At other times, nominal loading only but box...

    FIRE RATED POLY SHEET

    We build sound proof enclosures for power generation. Our insulation system includes a vapour barrier. Our current choice carries a decent fire rating, but still performed badly in an actual fire. Since this additional precaution seems to have bought us little, we are considering substituting...

    does any poly sheeting have a fire rating

    We build sound proof enclosures for power generation. Our insulation includes a vapour barrier. Our present choice carries a good fire rating, but still preformed badly in an actual fire. Since this additional precaution seems to have bought us little, we are considering substituting 6 mil...
