I. Structral pallet racking
Structuralpallet rack systems are very similar to roll formed pallet rack systems except the horizontal load beams are attached to the uprights with bolts and have much greater weightbearing capacity. The bolt fixings make this a form of adjustable shelving racks can be constructed, reconfigured, and dismantled and reused as necessary.Structural pallet racking can be designed into the structure of the building itself, so that the upright columns are simultaneously used to support the roof of the storage facility, in which case the structural pallet rack uprights replace the storage building’s vertical support I-beams. This system is a rack supported building.
· 100% accessibility to individual pallets
· Easy picking lower levels
.Good storage density
· Easily installed and repositioned
· No special lift trucks required
· Applications: warehouse & logistics, food/drug distribution, petroleum/chemical plants, automotive distributors, big box retail hardware and home improvement stores.

III The difference between starting bay and extension bay
To build the Starting Bay, pick 2 assembled upright frames and 2 beam pairs. To build an extension bay ( Add-on Bay), pick 1 assembled frame (same depth as starter bay), and 2 beam pairs.
1. Load beams(also called step beams or box beams).
o Most step beams are roll formed members with a step along the top inside edge. This step is used to hold any load support components such as pallet supports or wire decks.
o Box beamshave no inset step, instead have four flat sides like a box. All load beams typically mount onto an upright frame column with integral rivets or hooks. Some systems utilize an extra clip or bolt to lock the beam to the upright.
o Structural beamsare hot formed structural C shapes with connecting clips at either end. Structural load beams are generally used with structural uprights but can be used with standard roll formed uprights. Structural load beams offer heavier weight capacities than step beams or box beams.
2. Upright frames(also called upright columns or uprights) vary in size and design depending on load requirements, and styles. The most common upright column is produced by roll forming flat coil stock steel into a modified "C" shape with returns. This style is often referred to as open-back roll-formed columns. Holes or slots are punched during manufacturing up and down the column at standard intervals so that the load beams can be mounted into the upright columns. Upright frames can also be constructed utilizing structural C shapes for columns. Structural uprights have an increased weight capacity over roll formed uprights.
3. Diagonal bracesand horizontal braces, commonly referred to as upright frame lacing is usually welded between two upright columns to form selective upright frames. The lacing may be bolted to the columns in some cases.
4 Row spacersare sometimes used if uprights are arranged in back-to-back rows; the spacers are mounted between adjacent columns to ensure that the rows are kept straight and to give the pallet racks even more strength and steadiness.
