Steel Walk doors

Deciding which steel walk doors to install in your steel building can sometimes be tricky. There are many factors to consider such as where do I buy steel walk doors and which type of steel walk doors do I purchase and often the choice is based on a convenient place to buy them rather than the most important factor which is the price and quality of the doors.

You must make sure that for every building, you consider each door for application and usage.  There is a guide that can help you with this, it’s called “Selection and Usage Guide” which has been created by The Steel Door Institute.  This guide can help with exterior and interior applications and is an excellent guide to determine choices.  The tougher the environment and the more frequent the usage, the more probable the need for heavier gauges and higher grades of hardware.  For example; if you are using a standard 20-gauge door and this is pretty standard for many applications, however a heavier 18-gauge door is probably the most recommended choice for entrance doors especially with higher traffic requirements.  You may also be looking at a heavy duty Grade 2 lock or a Grade 1 lock which might be necessary in this situation rather than a light of medium duty Grade 2 or 3 lock. There is a huge variety so it’s important to research these more thoroughly before making a final decision. Keep in mind that there are other key choices to be made with larger pricing implications not just gauges of doors, frames and grades of locks.

A typical choice is the door core. Exterior doors should have an insulated core, with polystyrene or polyurethane filler. Polystyrene is the most common and cost effective and typically carries an R-value of around 4-5.  Here is a little bit more info on Polyurethane, in case you are not familiar with it. They are widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets and much more.  It is any polymer consisting of a chain of organic units joined by urethane (carbamate) links. Now back to the R-Value, something to consider on your door is the R-Value.  This will include the frame and components of the door.  Because doors and constantly being opened and closed, the seal on the door has a much greater impact than a static door R-Value and this is based on the warm and cold air that passes through the system. So you need to ensure that the doors are well sealed through a high quality screw on or kerf type weather seal and the cost will illuminate your need for a polyurethane core ensuring the best economic fit is provided.
