|*Steel volume fraction 3-7%. Mechanical properties can be adjusted by changing steel grade and volume fraction
DUCON® and MicroMat® trade names and patents are owned by DUCON GmbH and are distributed exclusively in North America by STRUCTURAL TECHNOLOGIES for strengthening and force protection applications.
Specialized Engineering Support Services
STRUCTURAL TECHNOLOGIES in-house team of force protection experts and application engineers work hand-in-hand with owners, engineers of record, blast consultants and general contractors to develop the best solutions from a wide range of products. By partnering with design professionals we assist in solution development by providing:
- Determination of blast loads and pressures
- Analysis of blast capacity and performance determinants
- Blast mitigation conceptualization and option development
- Detailed high-fidelity analysis and design of mitigation options
- Structural design of blast mitigation solutions
Each product in STRUCTURAL TECHNOLOGIES force protection line can be custom engineered by our application engineering group to adjust to your specific project needs. Often multiple product solutions are combined and modified to optimize both performance and value.
Collaboration with our in-house contracting services that understand constructability, schedule and construction costs ensure all elements of the project are taken into account in developing the highest value solution.
