Welcome to Meca Enterprises Inc.

Meca is a Stack Solutions company.  We offer Engineering solutions to common problems encountered by steel stack designers, fabricators, end users and OEM’s.  We do not fabricate stacks but we do offer Engineering solutions to help our clients design and fabricate steel stacks.



Engineering Software

We provide software solutions for Structural Engineers. We offer the only software specifically written for steel stacks in the world and one of the most cost effective wind programs available.



Stack Vibration Dampers

Meca Enterprises offers Damping Pads and Tuned Mass Dampers (TMD) to solve Vortex Shedding problems commonly known as Stack Vibrations.



Engineering Services

We can provide Structural Engineering services for stacks, air coolers and other structures. We are licensed in several states as well as Alberta and British Columbia.



Questions? We’re here to help

Whether you are a new or existing software client or debating to subcontract your work to Meca, we offer unparalleled support.



MecaStack Software

MecaStack is the most widely used software in the world for designing self-supported and guy wire supported steel stacks. An easy to use Windows based interface allows designers to quickly model a stack. The user has complete control over the codes that are used for Along Wind, Across Wind, Stress and Fatigue. Load Combinations and factors can be customized as needed.


MecaWind Software

MecaWind is a cost effective program used by Engineers and designers to perform Wind calculations per ASCE 7-10 and ASCE 7-16.  The program is simple to use, and offers a professional looking output with all necessary wind calculations. The user also has a great deal of conrol at their fingertips to customize their output to suit their needs.


Wind Example e-Book

Our new EBook provides a detailed set of wind load calculations that illustrate how to calculate wind loads per ASCE 7-10 and ASCE 7-16. In addition, the EBook provides a comparison of the various methods within each standard as well as a comparison in the results obtained following ASCE 7-10 versus ASCE 7-16.


Damping Pads

Meca provides damping pads for stacks. Generally these are an economical solution for stack heights from about 50 ft [15.2 m] to 150 ft [45.72 m].

It’s a very easily solution to implement on New Stack designs. Damping pads have been used for about 40 years, and have proven to be very reliable.


Tuned Mass Dampers (TMD)

A Tuned Mass Damper (TMD) is device that is added to the top portion of the stack that increases the damping of the stack, which will suppress wind induced vibration.


Tuned Liquid Dampers (TLD)

Meca has partnerships with companies that design Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD). These are typically used on stacks that are 150 ft [45. m] and taller. There are many factors that determine whether a TMD or TLD is more appropriate.
