Section XXXXX – 4-Post Fixed Storage Units

PRODUCT

2.1 MATERIALS

A. Upright frames

Upright frames are made of two or more cross members mechanically assembled without screws or rivets to join the top and bottom (and center if necessary) of the post and form a rectangular upright frame. The post is made of 16-gauge 1 ¼” x 1 ½” rectangular shaped cold rolled steel. The post is slotted on each side at every one inch increment. The slots are 3/16” wide x 5/8” long and are designed to accommodate a variety of shelf and roll-out drawer configurations. The back of the post is also slotted at every 1 ½” increments. Posts are made of two rows of slots, side by side from top to bottom. Slots are 3/16” wide x 5/8” long, including 3/8” between the two rows. These slots are made of 16-gauge steel folded in a “U” shape channel at both ends with an integral safety “keeper” to the same time. Thus the uprights must allow for component integration on either 1” or 1 ½” increments depending only on the selected shelf component.

B. Cross members

Cross members are 4” high x ½” wide. They are made of 16-gauge steel folded to create a “U” shape channel. At both ends, hook type design allows to snap the cross members in both rows of slots at the same time. In seismic zones, the cross members are welded to the post.

C. [Levelers for fixed units only] Each post shall have an integrated leveler which allows for ¾” adjustment to accommodate for uneven floor surface. No temporary shims or other third party leveling device will be accepted.

D. Center back panel [optional on double face sections] Center back panels are made of 20-gauge steel and constructed in such a way as to form and integral finished product.

E. Full back panel [optional for single sections] Full back panels are made of 20-gauge steel box formed ½” thick and affixed to the post to form an integral finished product.

F. Supported type

1. Full-depth shelves : Full-depth shelves are made of box rolled formed 22‑gauge steel, with “Four Bend” ¾” edge construction which adds additional strength and capacity as well as it creates a hidden safety edge to protect people and items. The full-depth shelves are supported by two longitudinal shelf supports and the appropriate number reinforcement channels. Shelves are also available in 18-gauge steel as an option.

2. Longitudinal supports : [¾” high supports] or [1 ¼” high supports for heavy duty application] are made of one “U” shaped 12-gauge steel channel. A standard formed steel claw is welded at each end to form a complete support. These supports are inserted into the slots located at the back of the post.

3. Front-to-back reinforcement channels : [¾” high reinforcement channels] or [1 ¼” high reinforcement channels for heavy duty application] are made of 12‑gauge steel formed in a “U” shaped channel and are sitting on the longitudinal shelf supports.

4. Base support : A 12-gauge steel special “U” shaped channel is provided for the bottom shelf. The support is inserted at the bottom of each post and anchored to the floor or to the carriage, in compliance with seismic standards.

G. Hooked type

1. All shelves and canopy tops shall be constructed of minimum 18-gauge steel and clipped on the uprights. Welded reinforcement can be added to accept heavier loads. Shelves floating on support are unacceptable.

2. All shelving shall be back-to-back shelves and shall have capability of being adjusted without use of tools. Canopy tops required on all sections.

3. All shelves shall be adjustable on 1” centers along the entire height of upright.

4. Maximum deflection under load; must maintain L/180 based on a uniform distributed load of 50 pounds per square foot.

H. Sway brace (required with hooked type)

1 1/8” wide sway braces are made of two 16-gauge steel bars, assembled with a rivet. Sway braces are connected to the posts by means of mechanical rivet or dowell pins. Sway braces are positioned where needed on taller shelving sections to add lateral stability.

I. End panels

Shall be constructed of 18-gauge steel, 1 3/8” thick, they are bolted to bottom and top upright cross members.

J. Side closure panels Shall be constructed of 20-gauge steel, they are formed to be flush with the edge of the shelving upright and bolted to bottom and top upright cross members.

K. Plain back stops (single entry)

Shall be 5 17/32” high formed of 20-gauge steel with a 3/8” bend on top and bottom and a 1 3/16” bend on each side.

L. Slotted back stops (single entry)

Shall be 5 17/32” high formed of 20-gauge steel with a 3/8” bend on top and bottom and a 1 3/16” bend on each side. Slots are located on 1” increments for divider adjustment.

M. Plain center stops (double entry)

Shall be 4 3/16” high formed of 20-gauge steel with offsets bends to center on upright frame.

N. Slotted center stops (double entry)

Shall be 4 3/16” high formed of 20-gauge steel with two offset bends. Slots are located on 1” increments for divider adjustment.

O. File dividers

Shall be formed of 20-gauge steel with one lug at the top rear and two lugs on the bottom to engage slots in the shelf for easy adjustment on 1” horizontal centers. The front top corner of the divider is rounded with an approximate 2” radius.

P. Sliding reference shelf

Shall be 11” deep by 30” wide, made of 20-gauge steel reinforced on each side with steel angles to secure slides. Shall operate on double extension ball bearing slides equipped with rubber bumpers on each end of travel. The assembly is securely attached to underneath the storage shelf, flush with the front edge.
