How can beveling be your secret weapon against rust?
Due to its versatility and durability, #steel is one of the most widely used materials to diverse applications across construction, manufacturing, and infrastructure. However, its susceptibility to #rust poses a significant limitation on its utility.
Impact of the weather conditions
The deterioration of steel is heavily influenced by weather conditions. Why? Iron, which is a key component of steel alloys, oxidizes when exposed to air and humidity. Damage resulting from #corrosion affects the properties of steel structures. Therefore, ensuring proper corrosion protection is a crucial aspect of working with metal constructions.
How to enhance its resistance to environmental factors?
Currently, there are two most common methods:
Both approaches aim to ensure the reliable performance of steel structures (for a specified period of time). While it is quite obvious that investing in corrosion protection is essential, it is worth noting that its cost-effectiveness depends on proper surface preparation. Surfaces with high porosity are particularly prone to rust, making sharp edges and corners of steel elements especially vulnerable to corrosion.
The importance of radius edge bevel
Before applying the coating, the surface of the alloy must comply to technical standards. Current directives such as EN 1090 and EN-ISO 12944 Part 2 specify the necessity of applying a soft or radius edge to all steel sections before painting. This prevents rust build up on sharp edges. The covered area must be smooth and with no sharp ends – as it significantly minimizes corrosion of steel.
The larger the bonding surface for paint and coatings, the lower the risk of peeling and corrosion. The most robust adhesion of the protective layer occurs when the edges of the steel are rounded. To achieve it, the edges of the steel may be rounded with a special type of beveling process – metal #rounding.

Failing to provide adequate protection for steel plates results in paint flaking over time and plate corrosion, especially in the area of sharp edges. Thus, creating a perfect #radius on material edges prior to painting holds crucial implications for the durability of the material cover.
How can beveling be your secret weapon against rust?
In most applications, bevelling means removing a specific volume of metal at a required angle along an edge prior to welding. In today’s market, there is a wide array of chamfering machines that eliminate the need for flame cutting and grinding procedures. These machines allow for various machining operations on plates, tubes, or pipes such as beveling, facing-off, “J” prepping, counter boring or cladding.
However, not every beveller has the ability to contribute to safeguarding against rust. What we need is a beveling machine specifically designed to produce a consistent, uniform radius, regardless of whether an R2, R3, R4 or R5 is required. Only then they meet requirements for corrosion protection and extending the longevity of steel structures
By producing a perfect radius on material edges, #PROMOTECH beveling machines boost protection against rust, extending the lifespan of steel. It’s worth highlighting beveller machines which are equipped with a practical single 45-degree 4 tip cutting head, capable of handling both V bevels and rounding, i.e. bevellers such as BM-7 , BM-18 and BM18A .
Depending on inserts in use, these machines can either do the bevel of the welding seam preparation or create the required size of smooth and consistent rounding. All that in just one pass, saving time and money over conventional grinding methods. By enhancing adhesion, bevellers effectively prevent rust, ensuring your steel endures the test of time.
In summary
While protective coatings are essential, rust protection begins by adequately preparing the bonding surface and ensuring a uniform radius on material edges prior to their application. Selecting a handy, reliable beveler able to properly perform rounding, enables the best outcomes.
