Structural Plate
Contech’s steel and aluminum structural plate offerings have a long
history of strength, durability and economy. These structures meet
a wide range of site specific challenges with a variety of sizes and
shapes available.
BridgeCor® structures have a 15” x 5.5” advanced profile,
reducing installation and maintenance costs while providing a
durable and corrosion resistant structure that clears spans up to 65’.
MULTI-PLATE® structures consist of field-bolted, galvanized steel
plates. Aluminum Structural Plate structures are similar to
MULTI-PLATE, but with basic plate material consisting of aluminum
instead of steel.
The strength-to-weight ratio of BridgeCor® makes it a cost-effective and
structurally efficient solution for limited access roads.
SUPER-SPAN™ – Corrugated Steel structures utilize the same
plates as MULTI-PLATE structures, but have special features that
allow for larger spans and a different family of shapes.

Erosion Control
Spillways and Diversion Channels
Hard Armor Solutions
ArmorFlex® is an engineering alternative to traditional channel
reinforcement, such as riprap or cast-in-place concrete. It is a
flexible, interlocking matrix of dry-cast concrete blocks of uniform
size, shape and weight. The matrix is laced with a series of cables,
which allows for the placement of large mats of block. ArmorFlex
systems combine porosity, flexibility, vegetation encouragement and
habitat enhancement in a hard armor solution.
A-Jacks® are high stability concrete armor units designed to
interlock into a flexible, highly permeable matrix. A-Jacks can be

products that provide an ideal solution for
spillways with a low life-cycle cost compared
to other permanent options.

High Performance Turf Reinforcement Mat (HPTRM)
Solutions
Pyramat® is a rolled, geosynthetic High Performance Turf
Reinforcement Mat (HPTRM) that is commonly used where erosion
control is critical, but a hard armor solution is not required.
Pyramat is composed of a unique, three-dimensional matrix
of polypropylene yarns designed in a uniform, dimensionally
stable configuration of pyramid-like structures. HPTRMs exhibit
extremely high tensile strength as well as superior interlock and
reinforcement capacity with both soil and root systems.

severe erosion challenges. This system is ideally suited to protect
stormwater channels in arid and semi-arid environments where
vegetation densities of less than 30% coverage are anticipated.
ArmorMax utilizes Pyramat HPTRM in conjunction with earth
percussion anchors to provide the highest performing rolled
erosion control system available.
