I don't think expansion will be a major concern. The main reason it is prohibited in some areas is because clay is an acid. Over time it will react with the steel and the concrete. Moisture would speed the reaction, so the lean concrete mat is a good thing. The reaction will be very slow and...
Or just unhook the cables at the motor end and insulate them. Then energize the starter and measure if there is any current flowing at all. It should be 0 Amps in each conductor if everything is ok. If there is a L-G leakage path you will read your 2.7A on one of the cables.
The Domex we use is mostly in structural applications - truck frames, low-boy trailers and excavator booms. In applications where impact and abrasion are the main requirements we use Hardox or ordinary AR plate. We buy directly from Swedish Steel, and we usually do our own plasma and laser...
We have also gone through the transition from A514 to Domex on a large number of products. From the standpoint of mechanical properties, there is no down side. There are only two disadvantages we have run into:
1. Domex is not available in as wide a range of sheet sizes and thicknesses as...
That's correct. As I understand it, the pulse start ballasts don't consume as much tungsten from the electrode surfaces when they start. The evaporated tungsten coats the inside surface of the arc tube in a standard metal halide bulb and turns it black after a short period of time, thus...
We've been using pulse start metal halide high-bay fixtures in buildings of that height. The light level doesn't drop as the bulb ages nearly as badly as standard metal halides do.
The installations we've been happiest with are ones where we have painted the interior of the structure white and...
Can anyone tell me what type of paint would be
best for cold weather application to structural
steel? We are erecting a metal building that
will see corrosive fumes and we want to paint all
the red-iron with a top-coat before installing
the roofing and siding.
The original plan was to spray...

They make several models and there are typical installation drawings for each. We have installed several of their dock levelers and have never had any problems.
