Stainless Steel
Gantry

EC&MW, manufacture’s both T Frame and A Frame style stainless steel cranes, although the A Frame model crane is not shown on our website.  The T Frames style is by far the more popular design among our customers.  Let’s talk about stainless steel for a moment.  It is as it says “Stain Less”.  You will always have some minor iron deposits at the surface.  This was caused at the time the stainless steel was made. Those iron deposits, in time, will turn to rust.

There are two types of stainless steel material  that we have available for manufacturing.  304L or 316L .  The “L” stands for low carbon.  We try to use L material whenever possible/available.  Without getting into a lengthy discussion regarding low carbon, it mostly has to do with the welding process.  Using L material or non L material isn’t going to make any noticeable difference under most circumstances.  304: We have manufactured gantry cranes for both food and pharmaceutical industries out of this material.  Although 316 is more corrosion resistance, since it has molybdenum where 304 does not.  316: Comes at a price.  This material is going to be approximately 20% to 25% more expensive and the availability is going to be more limited.  We have also built cranes for food, pharmaceutical and sewer treatment facilities from 316.  Sewer treatment plants try to use 316 stainless whenever possible, especially in areas where heavy amounts acids and corrosive gases are present. What it really comes down to is what your particular industry standards require. For more info on 304 vs 316 stainless Steel.
