Erwinville, LA Dusk

At Trinity Lightweight™, we aim high when it comes to providing expanded shale and clay lightweight aggregate of the highest quality.

Each production facility has a quality control plan in place to ensure consistency in unit weight and gradation of the product going to each customer. The QC plan at each plant aligns with that of our other plants, so even though the lightweight aggregate at each plant has its own unique properties, those properties are constantly monitored and controls are adjusted to maintain consistent quality.

While our aggregates are produced to meet the requirements of ASTM C330, Specification for Lightweight Aggregates for Structural Concrete, and ASTM C331, Specification for Lightweight Aggregates for Concrete Masonry Units, our QC plans ensure that we exceed those requirements.
