Different Holes In Warehouse Racking

When installing the racks, we can observe that many warehouse racks can be installed without welding. The main reason is that the beams are hung on the column holes to fix the beams. Through observation, it is not difficult to find that sometimes the hole pattern of the column hole on the column is different, so why does the column have a different hole pattern? What are the differences between these different hole types?

1. Teardrop Style

Teardrop, also known as Interlake Old-Style, is the most popular type of pallet racking in the country. This style can be identified by looking at the pin connector on the load beam or the slot connector on the upright. The slots on the upright look like an inverted teardrop, making this style very easy to identify on uprights. The load beams have circular pins that fit in the upper part of the teardrop, dropping down and smoothly locking into the upright.

2. Newstyle

This is a good type of pallet racking if you are looking for used pallet racking because Newstyle is compatible with Teardrop style racking. You can connect Newstyle load beams with Teardrop (Interlake Old-Style) uprights. Newstyle uprights can be identified by the slot connector on the upright. It has a rectangular shape with a slight inward slant towards the bottom. The Newstyle beams are also offered in a shaved pin style or tooth pin style. The pins are spaced 2” or 4” apart center-to-center.

3. Structural Style

Structural racking is an extremely durable and versatile type of pallet racking while having a simple construction and connector type. Structural style uprights and beams are constructed from hot rolled steel and are highly impact resistant and designed for greater weight-bearing capacity. Instead of utilizing hooks or pins to connect with uprights, Structural load beams utilize bolts which bolt directly into the uprights. Structural uprights come in single column or closed post column styles offering additional reinforcement for greater load capacities.

4. Speedrack Style

Speedrack is known for its unusual hole pattern and beams that have no pins or hooks. The beams attach to the uprights through a U-shaped bracket connection. The hole pattern on the upright consists of circular holes located directly on both edges of the face of the column and are spaced vertically 4” apart center-to-center. U-shaped brackets pass through these holes from one side to another and are secured with a J-hook to lock in the load beam to the upright.

5. Ridg-U-Rak Style

Ridg-U-Rak style racking has rectangular slots located on the uprights where the hooks connect. Ridg-U-Rak uprights have an outward bend on each internal side of the column. The beams have hooked flanges, resting against the ridge of the upright. The beams are more thinner than other beam styles and feature hooked connections. Ridg-U-Rak also use a spring component with two pins as a lock that is installed inside the upright column.

6. Keystone Style (also known as Republic)

Keystone (aka Republic) racking utilize a hook & slot connection. Keystone style has a trapezoidal hole pattern on the upright. These slots are located on the center of the face of the column. The beams are roll formed and feature hooks that slide into the slots on the uprights. The beams are secured to the uprights with J-hooks or a removable steel clip.

7. Penco Style

Penco style racking also use a hook & slot connection. The uprights are identified by the side by side slanted narrow slots and beams with slanted hooks that fit snuggly into the slots on the face of the uprights. The beams also have a tapered look to them when you look at the cross section. These beams are locked into place with a sliding lock incorporated into the beam.

8. T-Bolt Style

T-Bolt style racking is another common variety of racking that can be identified by the rectangular slots on the columns and the similar slots on the load beams. T-Bolt beams are attached to the uprights with large bolts that have to be tightened properly. The standard T-Bolt connection has a bolt on each end which holds the beam in place. T-Bolt load beam connections are available for high seismic design areas. T-Bolt racking most commonly has Blue uprights and Yellow load beams.

Shelves are very important storage equipment for warehouses. Therefore, when companies purchase a large number of storage shelves, they still need to choose carefully according to their actual needs.
