Is there a minimum temperature to bend rebar? We have a legit bar bending operation at our construction site so I am not worried about bend radius and the like as we have machines that govern all that. But there was a question thrown out if there was a minimum ambient temperature to perform the bending. Section 7.3 of ACI 318 talks about heating the bar to bend to avoid cracks, but nothing about a minimum temperature. We will of course inspect the bar for cracks after we bend, but would like some input on if any knows of another code that would govern the min temp for bending operations. Thanks - Forrest

When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final productâ€™s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
With all of the hype around 3D printing, it can be easy to get lost in fascinating, intricate metal parts made with additive manufacturing. These parts, while impressive, are probably dissimilar from many of the parts you currently produce or use. So why invest in metal additive manufacturing? Download Now
Construction was at one time a highly regionalized business. Pragmatic and market forces made it more efficient for even a large, industrial general contractor to focus regionally. But inexorable trends are making it more important for major commercial, civil, engineering and industrial contractors to grow their global footprint.
