Description

This is a 1×4 (measures 0.75" × 3.5"), 36" length of Tangent poly lumber in the Black color. MATERIAL INFORMATION Poly lumber is an eco-friendly, innovative product crafted from high-density polyethylene (HDPE), offering all the benefits of wood without its common limitations. Engineered for durability, these plastic boards resist rotting, cracking, and degradation, making it ideal for non-structural outdoor applications like furniture, playground equipment, and park amenities. Built-in UV stabilizers preserve vibrant colors over time, ensuring a long-lasting, low-maintenance finish. This versatile material is not only durable but also remarkably easy to maintain. Many substances like paint, chemicals, and other materials do not adhere to HDPE as they do to traditional materials, making cleaning a breeze. Most dirt and grime can simply be washed off with soapy water. Poly lumber is also straightforward to work with, as it is compatible with standard woodworking tools and fabrication techniques. This sustainable building material is an excellent wood replacement for almost any construction project, including boardwalks, chairs, tables, park benches, signs, boat docks, and much more. HANDLING & CARE Poly lumber is low-maintenance and easy to care for. For general cleaning, simply use a mild dish detergent and water, scrubbing with a soft-bristled brush, and rinse thoroughly. For deeper cleaning, a pressure washer on a light setting (below 1,500 psi) can be used while keeping the nozzle 10-12 inches away to prevent damage. Avoid harsh chemicals; test any new cleaning solutions on a small, hidden area first. For tough stains like rust or oil, apply a rust remover or penetrating oil and scrub gently before rinsing clean.

Great product! We used this to trim out the bottom of a metal fence post anchored into cement. Needed something weather resistant because of the amount of rain we get here.

Hubby is redoing my dining room and got these to use as shelves in the large standing cabinets he purchased. They are perfect to cut to size and work great in my new pantry cabinets.
