We are looking for a product to use for where a 24KCS5 open web steel joist roof framing that intersects a 2 hr rated barrier gypsum board wall with 3-1/2" metal studs. The roof is a 1 1/2" metal roof with 5" rigid polyiso insulation. Need design for the metal barjoist penetrating 2 hr fire barrier. floor is concrete 

We have this project and we are using 1" HAS rod, 12" embed, RE-500 Sd epoxy. It has been brought to my attention perhaps there is an issue with the installation. It seems some of the rods installed are slightly out of plumb, we can say this because of the projection of the rod over the concrete surface, there are some that ar...

Ref. attached drawings. These 1" anchor bolts were not cast-in-place when the bond beam was filled in this masonry stair shaft. The engineer has requested an adhesive Anchor Bolt be proposed with stamped calculations as an alternate.  Is this something that Hilti can provide? 

My company must often anchor from floor to ceiling with a strip of plate (such as a door jamb). The predominate load is shear (parallel to the vertical wall). Almost every time we do, we have trouble estimating the amount of concrete that should be included above (at the ceiling) and below(at the floor). When dealing with o...

Please provide me a detail of a 1 hour rated cmu wall up to the bottom of a cast in place concrete floor. The gap does not exceed 2 inches. HW-D-1058 will work but I need the same for a one hour wall instead of three hours. Thank you.

For the allowable expoxy products. HY-200 has been broken out into A and R types. Are both approved for these deep embedments or only HY-200R?

Traditionally HILTI tables indicated the required embedment lengths to develop either the yield strength or the tensile strength of the rebar. These published embedment lengths were substantially less than ACI embedment lengths for CIP rebar. Why do we now need to embed post-installed rebar for ACI embedment lengths as oppos...

Does Los Angeles approve the use of Hilti products as post installed rebar? If so where can I find any additional requirements for lap splices?

For a group of anchors suppose all anchors are mechanical anchors except one which had to be epoxy set, can the software analyse this situation or any tips to consider when this situation arises.
