Our commitment to lead and advance the field of seismic bracing has built the Loos & Co. reputation as pioneers in the field since 1993. We continue that tradition with the introduction of the Loos & Co. Engineers' Tools Seismic Calculator. After months of planning we are proud to introduce this web-based, mobile-responsive resource capable of completing the complex calculations required to create code-compliant seismic bracing designs.

The Engineers' Tools Seismic Calculator will process all of the complex NFPA-13 seismic calculations from your designs and produce a completed NFPA-13 form to submit to the Authority Having Jurisdiction (AHJ). If your project conditions change, the calculator allows you to easily edit your design.

Along with the ability to print submittal documentation, our Seismic Calculator will generate a complete bill of materials to be submitted to your local Loos distributor for quoting. 

Loos & Co. is excited for the opportunity to make your seismic bracing projects easier and less time-consuming. We invite you to discover how our Engineers' Tools Seismic Calculator can streamline your seismic bracing project requirements. 


Key Features of Loos Seismic Bracing Systems Calculator:

• Utilizes current seismic code data
• Optimizes your design specifications
• Accessible online free of charge
• Generates Bill of Materials for easy quoting
• Suggests cost-effective design alternatives
• Performs complex NFPA calculations

In today’s environment of new Seismic Bracing Codes and retroactive enforcement policies, the term RETROFIT might be on a lot of minds these days. What are your options when the code requires that past jobs be retrofitted to be compliant with current codes? In all too many instances the existing installations of HVAC and other mechanical systems, plumbing systems, and electrical cable trays, leave very little room for the installation of new seismic bracing components for Fire Sprinkler applications. Attachment of the braces to the building structure is critical, as is spacing requirements and the horizontal load factors of the bracing components. All of these factors combined can make new code compliance difficult and very expensive; especially if re-installation of entire fire sprinkler systems is necessary.

The fully Code-Compliant Seismic Bracing Cable by Loos & Co., Inc. ( offers a solution to this dilemma. Loos & Co, Inc. is headquartered in Naples, FL and has been active in the Fire Suppression Industry for over 20 years.  You may have seen Loos exhibiting at key industry trade shows such as AFSA, NFSA, and NFPA. Loos supports all of these associations.
