unistrut concrete inserts

Maximum Support for Your Projects

Broadest Range of Concrete Solutions

With the widest range of styles and accessories in the

industry, Unistrut concrete inserts give you more ways

to design and build your structures. They are available

in a wide range of finishes and materials, including

stainless steel and both polyester and vinyl ester fiber-

glass, offering advantages for every application… even

highly corrosive environments.

From office buildings and airport terminals to plants,

hotels and service tunnels, Unistrut offers concrete

inserts to solve all your insert application requirements.

Delivery from Local Inventories

Unistrut Service Centers stock most standard Unistrut

components and are located in principal cities through-

out the United States and Canada to serve you quickly

and directly.

Technical Service

Unistrut Service Centers are equipped to provide a

range of technical support for any concrete anchoring

project. These and other

important value-added

services are part of

every concrete insert

we manufacture.

Custom Fabrication

The inherent versatility of Unistrut concrete inserts seldom requires

special sections or fittings. To satisfy special requirements, however,

Service Centers can custom fabricate special inserts, connectors or

accessories to your specifications.

“J” hangers can be attached directly to the concrete insert to support pipe or conduit.

Metal framing combined with insertsprovides support service tunnels.

The heavy duty inserts are usedto support the facia.

Concrete inserts are an ideal solutionfor drop rod support of trapeze.

UNISTRUTConcrete Inserts 3


The Unistrut concrete insert is firmly fixed to the concrete side of the form before pouring. When the forms are removed,the insert is ready for use. Brackets and other components can be attached at any point of the continuous entry channel.

Concrete Inserts

MATERIALCold-formed inserts are manufacturedfrom standard 12 gauge (2.7 mm)Unistrut channel sections conformingto ASTM A570 GR 33 or ASTM A653SS 33, unless otherwise noted.

Hot-rolled inserts, as noted, aremanufactured from carbon steelmeeting physical requirements ofASTM A283 GR D.

To inhibit concrete seepage, allinserts (except spot inserts) areprovided with closure strips and endcaps or foam filler, unless otherwiserequested.

Most concrete inserts are available instainless steel on special order. Consultfactory for ordering information.

DESIGN LOADDesign loads, where shown, are basedon 3,000 PSI concrete, unless noted.

STANDARD LENGTHSInsert lengths range from 3 inches(76 mm) to 20 feet (6.10m) with atolerance of ±1⁄4-inch (6.4mm).

DIMENSIONSImperial dimensions are illustrated ininches. Metric dimensions are shownin parentheses or as noted. Unlessnoted, all metric dimensions are inmillimeters and rounded to onedecimal place.

Custom-designed inserts are availableon special order. Consult factory forordering information.

APPLICATIONA wide range of heavy-duty to light-duty “continuous” and “spot”concrete inserts are available for usein pre-cast, pre-stressed or poured-in-place concrete floors, walls orceilings.

FINISHESCold-formed, standard-duty, light-dutyand spot concrete inserts are avail-able in Perma-Green II (GR), hotdipped galvanized (HG), conformingto ASTM A123 or A153; pre-galva-nized (PG), conforming to ASTMA653 SS 33 and plain (PL).

Hot-rolled inserts are hot-dippedgalvanized (HG) conforming to ASTMA123 or A153.

• Closure strip P3712 P and a styrene bead end cap that fits inside thechannel to inhibit concrete seepage are included.

• The recommended design load when used for curtain wall anchorage is5,000 pounds and is based on use in average, good concrete. The design

load includes 1⁄3 increase in load as permitted by AISI Specifications andUniform Building Code when stresses are produced by wind or earth-quake and other loads.

• The recommended design load is based on using two P1010 nuts at noless than 3" O.C. and no closer than 2" to either end of the insert. Thedistance between the insert centerline and the concrete edge must be aminimum of 3".

• All nuts and fittings for P3200 series concrete inserts will fit.
