FAQ

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q: Can a steel square be used for checking the flatness of a wall stud?: No, a steel square cannot be used for checking the flatness of a wall stud. A steel square is a measuring tool that is primarily used for marking and measuring right angles. It is not designed to assess the flatness or straightness of a surface. In order to check the flatness of a wall stud, a straightedge or a level should be used. These tools provide a more accurate measurement and can determine any irregularities or deviations in the surface.

Q: How do you use a steel square to check for plumbness in a post?: To use a steel square to check for plumbness in a post, follow these steps: 1. Position the steel square against one side of the post, making sure it is flush with the edge. 2. Hold the steel square vertically, with one arm of the square touching the ground or a level surface. 3. Look at the other arm of the square and observe if it is parallel to the side of the post. If it is, then the post is plumb. If it is not, then the post is not plumb and needs adjustments. 4. To adjust the post, you can use shims or wedges to make it plumb. Place the shims or wedges between the post and the ground or the support to level it. 5. Repeat the process on all sides of the post to ensure it is plumb from all angles. Using a steel square is an effective method to check for plumbness in a post as it provides a straight and reliable reference line. It ensures that the post is perfectly vertical, which is crucial for stability and structural integrity.

Q: How do you use a steel square for cutting rafters?: In order to cut rafters, there are several steps to follow. Begin by marking the desired pitch of the roof on the rafter timber. The pitch refers to the slope or angle of the roof, and this information can typically be found in building plans or by measuring an existing roof. Next, position the steel square on the timber. Place the long arm (body) of the square along the edge of the timber and extend the shorter arm (tongue) towards the middle of the timber. Align the edge of the square with the previously marked pitch. Once the square is correctly positioned, use a pencil or marking knife to trace along the edge of the square, marking the timber. This will create a straight line that represents the rafter's angle. After marking one side, rotate the square and align it with the opposite edge of the timber. Repeat the process of tracing along the edge to mark the second side of the rafter. Now, you have a clear outline of the rafter shape on the timber. To cut the rafter, carefully follow the marked lines using a saw. Take your time and ensure the cuts are straight and accurate. It is important to note that if you need to cut multiple rafters, you can use the first one as a template for the others. Simply align the steel square with the already cut rafter and trace along the edges to mark the remaining ones. Using a steel square for cutting rafters is a precise and dependable method that guarantees the correct angles and dimensions for a successful roof construction.

Q: How do you use a steel square for creating precise miter joints?: Achieving precise miter joints using a steel square involves the following steps: 1. Begin by selecting an accurately calibrated steel square with clear markings. Ensure it is in good condition, free from rust or damage. 2. Measure and mark the desired angles for the miter joints on the wooden pieces you are working with. Typically, miter joints are cut at a 45-degree angle, but this may vary depending on your project. 3. Place the steel square along the edge of one of the wooden pieces, aligning it with the marked line for the miter joint. 4. Securely hold the square against the wood and use a pencil or marking knife to mark the cut line along the square's edge. Ensure the marking is clear and precise. 5. Repeat this process on the other wooden piece, ensuring both pieces are accurately marked and aligned. 6. Once the marking is complete, use a miter saw or hand saw to cut along the marked lines. Take your time and make precise cuts to ensure a tight and accurate miter joint. 7. After cutting, test-fit the two wooden pieces together to verify the accuracy of the miter joint. Make any necessary adjustments or refinements to achieve a perfect fit. Creating precise miter joints with a steel square is a simple process that requires precise measurement, marking, and accurate cutting. By following these steps and paying attention to detail, you can achieve seamless and clean miter joints for your woodworking projects.

Q: Can a steel square be used for stair stringer layout and construction?: Stair stringer layout and construction can indeed utilize a steel square. This multifunctional tool, alternatively referred to as a framing square or carpenter's square, is adaptable for various construction undertakings, including the arrangement and cutting of stair stringers. Comprising of two arms, one long and one shorter, conjoined at a 90-degree angle, this square permits precise measurements and angle layout, rendering it suitable for determining the rise and run of each stair step in a stringer. The long arm can be employed to indicate the rise, while the shorter arm can be employed to indicate the run. By aligning the square with the stringer board and marking the pertinent measurements, one can effortlessly carry out stair stringer layout and construction using a steel square. It is, however, imperative to ensure that the square is accurately calibrated and that the measurements are precisely transferred to avert any discrepancies during the construction process.

Q: Can a steel square be used for checking the squareness of table legs?: Indeed, one can utilize a steel square to verify the squareness of table legs. Boasting a multifaceted functionality, the steel square is a frequently employed instrument in the realms of carpentry and woodworking. Characterized by its 90-degree angle configuration, it facilitates a straightforward assessment of whether the table legs are perpendicular to the tabletop. Placing the steel square adjacent to the table leg and ensuring its impeccable alignment with both the vertical and horizontal sides enables one to ascertain the leg's squareness. This factor proves crucial in guaranteeing the table's stability and optimal operation.

Q: What are some common applications for a steel square in roofing installations?: Some common applications for a steel square in roofing installations include measuring and marking angles, cutting rafters and other framing materials, checking for squareness and straightness, and laying out roof lines and slopes.

Q: Can a steel square be used for checking the squareness of a concrete form?: Yes, a steel square can be used for checking the squareness of a concrete form. The straight edges of the steel square can be aligned with the edges of the form to ensure that they are at right angles to each other. This helps in maintaining the desired square shape of the concrete form.

Q: Can a steel square be used for measuring the thickness of tiles?: No, a steel square cannot be used for measuring the thickness of tiles. A steel square is a tool primarily used for measuring angles and ensuring accurate 90-degree corners. It is not designed to measure thickness. To determine the thickness of tiles, one would typically use a caliper or a thickness gauge specifically designed for measuring small dimensions. These tools are more precise and provide accurate readings for tile thickness.

Q: How do you use a steel square for marking roof gable angles?: To use a steel square for marking roof gable angles, you would first align one edge of the square with the roof ridge and the other edge with the gable fascia. Then, you can use the markings on the square to determine the desired angle and make accurate markings on the roof for cutting or framing purposes.
