Pallet racking is one of the most effective ways to maximize storage space and is commonly used in many industries. There are many different sizes and weight capacities that can accommodate a wide variety of applications. But, when adding to the existing pallet rack, it is important to take key steps to match the rack already in place. By doing so, you will ensure that the new pallet racking added will be compatible with the existing racking.
Before you start, it's important to understand a bit about the racks you have. The majority of all rack systems manufactured have a design for storing standard (traditional) items. The pallets on your racks are generally standard sizes (40 "x 48", 48 "x 48", 48 "x 42" or 40 "x 40"). The same goes for boxes, cartons and bins. All are based on standard dimensions to ensure maximum storage capacity. Is this an accurate description of your existing racks? Otherwise, you probably have a custom-designed rack.
Standard (selective) shelving has incremental beam dimensions one foot long. Beam lengths for standard shelving tend to start with four-foot lengths and increase from there. Custom rack lengths can be larger than one foot.
Beam length: there is a right way and a wrong way to measure sleepers. The correct method for measuring a cross member is to start inside a vertical frame and measure its length inside the opposite vertical frame. The typical beam length for standard racks is between 4 ′ and 9 ′.
Beam face: Then measure the face of the beam. To do this, measure the front of the beam from its top to the bottom of the beam. Why is it important? The face measurement gives you an indication of the weight that the beam can support. A large beam face supports heavier loads while a small beam face supports less.
Four measurements must be taken when vertically measuring a pallet racking. The first measurement is the depth of the upright. This is done by measuring from the outside edge on one side of the upright to the outside edge on the opposite side. Some common sizes are 36 ”, 42”, 46 ”or 48”, but sizes may vary especially if the amount is a custom size.
The next measurement is the size of the amount column. This part of the upright is where the beams lock into the upright and can be identified by the holes in it. First, measure the outside of the column, then measure the inside. You should have two measurements that will give you the size of the column. For example, by measuring the face on one side and the face on the other, I could get a measurement of 3 "x3". The size of the upright column coincides with its weight capacity.
Then measure the base plate. The base plate is what the vertical columns sit on. They usually have holes that allow them to be anchored to the ground. To get this measurement, measure the length and width of the pallet.
After measuring the pallet, we take our final measurement of the amount to find the total height. This is done by measuring from the ground to the top of the stud or from the top of the stud to the ground. The height is usually in one-foot increments, but could also be in between. Some common sizes are 8 ’, 10’, 12 ’, and 16’.
Measuring the decking is easier once you measure the depth of your rack. The two measurements must be identical. So if you are measuring using the front of the cross member at the back of the rack, the wire decking should be the same size (a cascading portion of the decking not included). It only remains to measure the width of the decking and simply measure its width from one end to the other.
Basic steps to match new racks to existing ones are not difficult. However, time, not a difficulty, frequently creates problems. If you are considering additional racks, contact a professional. They can measure existing racks, recommend options that you may not have considered, and manage the installation.
