For monthly purchasers, this will continue until you notify us you no longer wish to participate. Your purchase will be added as a line item on your bill. Solar – 5.5 cents per kilowatt-hour (kWh)ĬORE members have the option of acquiring RECs as a one-time or monthly purchase.We obtain RECs through wholesale power purchases and we do not add any additional fees to REC transactions. While many private companies offer RECs and similar commodities, CORE has created an REC program that makes the purchase of RECs affordable and easy for our members. Though REC participants do not receive green power to their home or business to a greater extent than any other member, RECs entitle them to claim the environmental attributes of the renewable energy represented by the RECs because the REC purchase has supported renewable energy production. RECs serve as certification that 1 megawatt-hour of electricity was generated from an eligible renewable energy resource and distributed to the grid. In addition, chromium increases the hardness of the steel, while the melting temperature, and vanadium also increases hardness while making it less prone to metal fatigue.Ĭontact M & K Metals for Rectangular Structural Steel Tubing Today Contact us for more information regarding our steel rectangular tubing product line, or request a quote today for an in-depth price analysis.CORE offers the purchase of RECs as a simple way to support renewable energy generation without the commitment to solar panels or wind turbine installations on your property. Nickel and manganese are often added to raw steel compositions to provide increased tensile strength and to promote increased stability within the iron-carbon solution. Steel is composed of mainly iron and carbon with smaller amounts of other elements that makeup the minority of the material structure. Rectangular Structural Steel Tubing Material Properties Other types of specific applications include the following: For these reasons, these materials are used extensively in construction, manufacturing, in machine part manufacturing, and even in art.

Since they are strong, relatively light and easy to weld, Square and Rectangular steel tubes are one of the most widely used materials for numerous types of applications. Depending on your project needs, we can provide you with steel rectangular tubing that will allow you to complete your job on time and on budget. 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. 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.
