Specification
Galvalume should not be used on, in, or around concrete or mortar. Concrete and mortar are highly alkaline environments. Bare Galvalume and painted Galvalume sheets suffer rapid corrosion when in contact with mortar and concrete. Bare Galvanized and painted Galvanized perform better in this type of environment.
While Galvalume has excellent durability in many settings, it should not be used adjacent to concrete or mortar.
Due to the high alkaline content in these environments, bare and painted Galvalume rapidly corrode.

- Q: I have never owned a non-stainless steel chef's knife and have been looking at some to buy recently, but all of them have various degrees of wear and use. They say that the wear is normal for non-stainless steel knives, but how can I tell if it is too much wear, or if the blade is clean?
- Carbon steel chef's knives out perform stainless in every aspect except 1, care. You can't put them in a dishwasher. Wash, rinse and dry off. Do not keep them in a drawer filled with other kitchen stuff, rather, keep them in a cabinet or block. If it starts to rust you can use steel wool to clean them up, or fine grit sandpaper if you want to retain a fine finish. For your viewing pleasure, a chef's knife I forged from crane cable.
- Q: What are the common quality control measures for steel coils?
- To ensure the performance and reliability of steel coils, several common quality control measures are implemented. These measures play a crucial role in upholding the overall quality of the coils and ensuring their compliance with the necessary standards and specifications. To begin with, dimensional checks are conducted to verify that the steel coils possess the correct thickness, width, and length. Deviations from the specified dimensions can significantly impact the coils' functionality and usability, making this check of utmost importance. Following that, visual inspections are carried out to identify any surface defects or imperfections such as scratches, dents, or corrosion. These inspections aid in identifying potential issues that could compromise the structural integrity of the coils or affect their aesthetic appearance. Moreover, mechanical property tests are performed to assess the strength, hardness, and other mechanical characteristics of the steel coils. These tests provide valuable insights into the coils' performance and durability under different conditions and loads. An essential quality control measure for steel coils is the analysis of their chemical composition. This involves scrutinizing the steel's composition, including the presence of any impurities or elements that may impact its properties. It ensures that the coils are made from the correct grade of steel and meet the required chemical specifications. Coating inspections also play a vital role in quality control. When steel coils are coated with protective layers, it is imperative to examine the adhesion, thickness, and uniformity of these coatings. This examination ensures that the coils have sufficient protection against corrosion and other environmental factors. Lastly, various non-destructive testing methods, such as ultrasonic testing, magnetic particle inspection, or eddy current testing, are employed to detect any internal defects or abnormalities in the steel coils. These tests enable the identification of issues like cracks, inclusions, or discontinuities that may not be visible through visual inspection alone. In conclusion, the quality control measures for steel coils consist of dimensional checks, visual inspections, mechanical property tests, chemical composition analysis, coating inspections, and non-destructive testing. These measures are vital in maintaining the quality and reliability of steel coils, guaranteeing their compliance with the required standards, and meeting customer expectations.
- Q: I had heard of steel braided fuel lines but ive also seen some air and coolant lines that are steel braided. Are these commonly used? I guess what I'm asking is if its a good idea to use them.
- Very good idea depending on the application. The steel braid reinforces the rubber to make it withstands pressure. Example, pressure side of power steering pump is reinforced, the return side doesn't usually need to be. Carbed cars usually run around 3-7 lbs on fuel line so no need, fuel injected cars run roughly 45 psi and up usually so those are braided.
- Q: How are steel coils used in the manufacturing of elevator components?
- Steel coils are used in the manufacturing of elevator components as they provide the raw material for producing various parts such as brackets, frames, and structural supports. These coils are processed through cutting, bending, and shaping techniques to create the necessary components that ensure the safe and efficient operation of elevators.
- Q: What are the common coil diameter and weight combinations available for steel coils?
- The common coil diameter and weight combinations available for steel coils vary depending on the specific requirements of the industry or application. However, some commonly available coil diameter ranges include 24 inches to 72 inches, while weight combinations can range from 3,000 pounds to 50,000 pounds or more. These dimensions can be further customized based on the needs of the customer and the capabilities of the steel manufacturer.
- Q: How are steel coils used in the manufacturing of electrical components?
- Steel coils are used in the manufacturing of electrical components as they provide a strong and reliable core for various types of transformers and inductors. These coils are often wound around a steel core to enhance magnetic properties and improve efficiency, allowing for the transformation and transfer of electrical energy.
- Q: Have spent two days making a specialized knife out of 304 stainless steel, after throwing into a log it bent slightly arghhhh. Is it worth continuing to finish it off or start all over again with different kind of steel if so which kind should i use.
- Sorry okorder /... I hope that link works but as you can see you dont want to use 303.304.316,410,416,430 You can get away with 301 but would be best to use 440. It kind of sounds like your a home shop guy. It would be best for you to make a knife out of a1 or d2 tool steel. with these steels you can torch heat them to a red hot heat where a magnet will not stick to them. Then let them cool slowly in the air. After that you can temper in a oven around 400f. This will a very hard long lasting knife. Check OKorder for good steel prices. A1 and D2 are not stainless but they are the best for a home shop. If you go stainless you can buy preharden material but you will have to grind everything. You can also pay someone to harden your knife but dont plan on it being cheap.
- Q: What is the standard thickness of steel coils?
- The specific application and industry requirements dictate the standard thickness of steel coils, which can vary. Generally, steel coils are obtainable in thicknesses ranging from 0.5mm to 10mm. Various factors, including intended use, structural requirements, and manufacturing processes, influence the desired thickness of a steel coil. Heavier applications that necessitate increased strength and durability typically employ thicker coils. Conversely, thinner coils are suitable for lighter applications where flexibility and weight reduction are crucial. To determine the appropriate thickness for steel coils in a particular application, it is essential to consult industry standards and specific project requirements.
- Q: What are the different certifications required for steel coil manufacturers?
- There are several certifications that steel coil manufacturers may be required to have in order to operate in the industry. These certifications ensure that the manufacturers meet certain quality and safety standards. One of the most common certifications is the ISO 9001 certification, which is an international standard for quality management systems. This certification demonstrates that the manufacturer has implemented processes and procedures to consistently meet customer and regulatory requirements. Another important certification is the ISO 14001 certification, which is an environmental management system standard. This certification shows that the manufacturer has effective environmental management practices in place and is committed to minimizing their environmental impact. In terms of safety, manufacturers may be required to have certifications such as the OHSAS 18001 or ISO 45001 certifications, which are standards for occupational health and safety management systems. These certifications indicate that the manufacturer has implemented processes and controls to ensure the health and safety of their employees and stakeholders. Additionally, manufacturers may need certifications specific to the steel industry, such as the American Institute of Steel Construction (AISC) certification. This certification is specific to structural steel fabrication and erection and ensures that the manufacturer follows industry best practices. Furthermore, manufacturers may also need certifications related to specific product standards, such as the American Society for Testing and Materials (ASTM) certification. This certification ensures that the manufacturer's products meet specific quality and performance requirements. It is important for steel coil manufacturers to obtain these certifications as they provide credibility and assurance to customers that their products are of high quality, environmentally responsible, and meet industry standards.
- Q: If a make a dish antenna of steel and of fiberglass, which would be more heavy and also which would be more expensive?
- Steel will be heavier but easier to manufacture. There won't be a huge weight advantage because you can use steel mesh which works the same as solid, near enough, as an electromagnetic reflector. Steel can just be pressed, fiberglass has to be laid up of resin and mat and then allowed to cure. Fiberglass will also need to be coated in something conductive whereas you can just spray paint the steel, or even buy it pre-coated.
