Available in S4S or rough surface finishes.Precision trimmed ends with clipped corners, painted and rodded.Solid sawn wood planks graded 2200F MSR 1.8E.The features of our scaffold planks include: In addition to these qualities inherent in southern pine, Kennison’s MSR pine planks exceed the common DI65 grading requirements and the standards set forth by OSHA and ANSI. Comparable strength and stiffness to other softwoods.Several features of southern pine make it highly reliable lumber, including: It has remained one of the most relied upon lumber products since colonial Americans first began milling it. More than 300,000 data points from tested samples provide evidence of its design values. Southern pine is among the most reliable species of lumber in North America. Kennison Forest Products exceeds all these standards with our DI65 and MSR planking. In addition to these standards, planks may be rodded on the ends to prevent splitting and cracking, clipped to minimize splitting when dropped on their ends, and may include MSR labeling information. Must be stamped with “Meets OSHA Standard 1910-28”.Labeling of moisture content (KD19 = kiln dried 19%).Must include the stamped logo of the grading agency.Stamped with the official grade of the specific wood specie (DI-65 for Southern Yellow Pine).Requires facing and stamping with the label “Scaffold Plank”.Grading agency must be accredited by the American Lumber Standards Committee.Grading official must be accredited by the grading agency to which the mill adheres, i.e.Deflection limits and span lengths for both wet and dry conditions according to OSHA Standard 1926.451 charts.To maintain safety standards for individuals working on wood plank scaffoldings, OSHA requires a minimum grade level. Scaffold Planks That Exceed OSHA Regulations In addition to the E rating of planks, MSR also provides a rating for flatwise bending design (F), ensuring a lower variability in bending from one plank to the next. Though our solid sawn wood planks must meet certain visual grading requirements, mechanical stress-rating equipment provides a more accurate measure of their modulus of elasticity (E). provides an upgraded type of machine stress rated (MSR) plank that meets and exceeds industry and regulatory demands. Unlike the typical DI65 (dense industrial 65) scaffold planks, Kennison Forest Products, Inc. Planking is critical for safe conditions on a scaffold and properly supports workers and their equipment. However, they can become slick during rainy weather, making them less desirable for certain applications.Kennison Forest Products is a distributor of 2200F MSR 1.8E Solid Sawn Scaffold Plank. Smooth boards, also known as S4S boards, are milled down and smoothed out, which creates a slightly smaller dimension. ![]() Rough cut boards are more expensive due to their board footage being slightly larger, but they are more slip-resistant than smooth boards. ![]() However, MSR 2200 planks have significantly less variation than visually graded DI65 planks, which makes them a preferred choice for high-risk work environments.Īnother consideration when choosing scaffold planks is their surface texture. Both DI65 and MSR scaffold planks are interchangeable and intended for the same application, as both meet safety requirements. It is important to know that MSR 2200 scaffold planks as well as DI65 scaffold planks meet stringent visual grading requirements in accordance with SPIB grade rules. On the other hand, MSR 2200 scaffold planks are individually tested by machines to ensure they meet specific strength and stiffness standards. DI65 scaffold planks are visually graded and use the density of the board to eliminate pieces that may not meet the published values. Two commonly used types of scaffold planks are DI65 and MSR 2200 scaffold planks. One of the most critical factors to consider when selecting a scaffold plank is its strength and stiffness. With so many options to choose from, it can be challenging to know which type of plank is right for your specific needs. They are used to provide a safe and stable platform for workers and their tools, equipment and materials. Wood scaffold planks are an essential component in any construction project where elevated work areas are required.
