Transportation Infrastructure
Transportation infrastructure projects involve complex specifications, long timelines, and coordination across multiple stakeholders, including engineers, contractors, and public agencies. M&K Imports supplies structural materials that support bridge, highway, rail, and heavy civil construction, with careful attention to compliance, documentation, and project alignment.​
H Piling
Structural H piling used in bridge repair, foundation systems, and heavy civil construction.
Materials are provided to meet ASTM and project-specific grades, sizes, and section weights, with custom lengths coordinated to structural drawings and engineering requirements. Mill-sourced materials are supported with inspection and documentation as required.
Wood Railroad and Timber Ties
Wood railroad and timber ties supplied for rail and infrastructure applications, sourced to specified species, grades, and
preservative treatment requirements, with inspection and treatment documentation coordinated to project standards.
Bridge Timbers
Bridge timbers supplied for transportation infrastructure applications where structural performance, treatment quality, and dimensional consistency are essential. Typical uses include bridge decking, stringers, caps, blocking, and other timber components associated with bridge rehabilitation and maintenance programs.
M&K Imports LLC supports bridge timber scopes by sourcing material to project-specific species, grades, sizes, and preservative treatment requirements. We coordinate closely with manufacturing and treating facilities to ensure compliance with agency specifications, retention standards, and inspection protocols, while aligning production and delivery with construction sequencing and site constraints. This approach supports dependable availability and long-term performance for active bridge programs.
I Beams
Structural steel I beams for bridges, buildings, industrial facilities, and civil infrastructure projects. Materials are supplied in accordance with ASTM and project-specific specifications, including required sizes, load ratings, and custom lengths, coordinated to approved structural drawings and engineering standards.
Concrete Railroad Ties
Concrete railroad ties for freight rail, passenger rail, and transit infrastructure. Products are sourced to meet AREMA and agency standards, including rail seat configurations, fastening systems, and dimensional tolerances required for system performance.
Crane Mats
Wood crane mats supplied for temporary access, load distribution, and ground stabilization on utility and heavy infrastructure projects. M&K Imports LLC provides crane mats manufactured from Southern Yellow Pine and mixed hardwood species, selected to meet load requirements and site conditions.
​
Mats are available in standard and project-specific sizes and thicknesses, including bolted or cabled constructions, and are coordinated through established manufacturing partners. We support scheduled programs and short-notice deployments, with logistics and unloading planned to match jobsite requirements and multi-location use.
