![]() M & K Metals is a leading provider of ASTM A500 verified rectangular structural steel tubing in a wide range of dimensional sizes. We also stock numerous Square Steel Tubing sizes, ASTM A500 Grade A within this spec is reserved for non-structural parts. If, however, you see the ASTM A500 designation on a print without a corresponding grade, please ask your engineer for additional clarification, since the minimum tensile strength of Grade C is higher than that of Grade B. Essentially, this means that the manufactured product is a square or rectangular steel tube that meets the structural specifications of ASTM A500 Grade B or C. It is worth noting that some of the structural steel items may contain the abbreviation “HSS,” which stands for Hollow Structural Section. ![]() A 10.6 radius of corners is also preserved so the corner section of the rectangular steel tubing does not exceed the set parameter of specified wall thickness. This type of quality control allows for a consistently well-maintained product that is strong and can resist stress from all directions, while being able to easily connect to other structural shapes. Rectangular Steel Tubing Properties & DimensionsĪSTM A500 verified rectangular steel tubing maintains established, clearly defined seams that are not located anywhere within the curvature of the tube. Some other beneficial qualities of rectangular steel tubing, include: Steel rectangular tubing also provides outstanding support and compression features, which allow this shape of steel to be used for a wide range of column applications. Rectangular steel tubing provides great strength-to-weight ratios, which means that less steel by weight is required to accomplish the job. Members who sign up still receive the same electricity from CORE they would otherwise receive.Structurally sound rectangular steel tubing maintains many different types of benefits, which makes it a highly sought-after material for a wide range of applications. Renewable energy is not actually delivered by these companies. This arrangement is essentially a purchase of wind RECs, similar to those offered by CORE. The member pays their bill to this new company, which, in turn, pays CORE what is owed for the member’s energy usage and collects an additional fee for this service. The companies claim that, for every kWh of electricity used by the member, a kWh of wind energy will be produced. We are aware of other companies promising to sell 100% renewable energy in our service area. Is CORE affiliated with companies marketing RECs to CORE members? Please consult your tax adviser for more information. Though members do not receive green power at their home or business, RECs generally are perceived as a way for energy users to claim entitlement to credit for the environmental attributes of renewable energy. Many people consider the purchase of RECs to be a simple way to support renewable energy generation without having to commit to solar panel or wind turbine installations on their own property. The RECs offered by CORE currently are generated by solar and wind farms in Colorado. Sign up for CORE’s REC program via this form.
