Pennsy Supply is the premier source in South Central Pennsylvania for high calcium white aggregate, which is used in cement, water conditioning, asphalt roofing, animal feed, and more. Pennsy also produces gray limestone and bright white limestone. Industrial-grade limestone fillers are used in carpet backing, grout, paint, caulking, cat litter, white cement, decorative stone, pelletized limestone, and more.



Pennsy Supply offers an extensive variety of asphalt, producing more than one million tons each year for customers ranging from large contractors to small paving operations. Pennsy asphalt mixes are certified by PennDOT for use on projects from residential driveways to major highways. Specialty DOT mixes are available upon request.



Pennsy Supply is the largest producer of aggregate in central Pennsylvania, producing more than nine million tons every year consisting primarily of crushed stone, sand and gravel.
