Metal fabrication is the process of building machines and structures from raw metal materials. The process includes cutting, burning, welding, machining, forming, and assembly to create the final product. Metal fabrication projects include everything from hand railings to heavy equipment and machinery. Specific subsectors include cutlery and hand tools; architectural and structural metals; hardware manufacturing; spring and wire manufacturing; screw, nut, and bolt manufacturing; and forging and stamping. The main benefit of metal fabrication shops is the centralization of these many processes that are often required to be performed in parallel via a collection of vendors.

RoboVent engineers are experts in every category of air filtration and ventilation. The four categories below represent the major options for treating your contaminated air. RoboVent has designed solutions for each of these categories and has manufactured air filtration systems of unrivaled quality.
For more information about these categories, see Indoor Air Quality Large blowers and air filtration equipment draw contaminated air from the plant typically at the ceiling level , filter it and return it to the plant. This is a proven solution in plants welding large parts with overhead cranes. It reduces the haze in the air, resulting in a cleaner working environment, with no negative pressure or heat loss.
Air in the immediate area of the welding activity is captured in a hood system, then filtered and returned to the plant. This is the best solution whenever possible.
It allows for a more flexible system and removes the smoke directly from the operator's breathing zone. There are many types of source capture, including overhead hoods, crossflow hoods, fume arms and fume guns, some of which work better than others. Large exhaust fans draw contaminated air from the plant and exhaust it directly into the environment, typically through the roof or walls. This is a traditional method and often results in negative air pressure.
Also, it is very difficult to climate-control your plant and the system may not work well in the winter.
Air in the immediate area of the welding activity is captured in a hood, sent through ductwork, and exhausted directly into the environment. This is a lower capital cost alternative to filtration, but tends to result in high operating costs and large, unsightly ducting systems that work less efficiently with modifications.
It also results in negative pressure problems. From bridges to buildings, structural steel undergirds our infrastructure and much of our economy. Structural steel's tensile strength and durability make it an ideal material for applications that require bearing heavy loads or withstanding shocks. It's also easy to weld and work with.
Some of the most common uses of structural steel include:. Structural steel is also used in a broad range of other building materials and heavy construction equipment. Of course, construction work for large structures like high rises and bridges happens outdoors and onsite. However, smaller structures such as playground equipment or stadium seating are usually assembled and welded in an indoor facility.
Structural steel fabricators also pre-assemble smaller components of larger structures that will be shipped to the construction site for final assembly. This may include drilling, cutting, grinding and welding of structural steel beams—all of which will produce dangerous dust or fumes. Fabricators working with structural steel face a number of challenges when it comes to indoor air quality. OSHA requires manufacturers working with structural steel to maintain a safe and healthy working environment for all employees.
They have set permissible exposure limits PELs for airborne contaminants, which may be different for General Industry, Construction and Shipbuilding.
No matter what industry sector a particular manufacturer falls into, failure to meet OSHA PELs can have significant legal and financial repercussions for manufacturers. Many manufacturers creating products with structural steel are finding that meeting these minimum standards is no longer enough to remain competitive and attract skilled workers. The American Welding Society estimates that manufacturers will see a shortage of , skilled workers by Maintaining a pleasant and safe workplace will help manufacturers attract and keep the best workers.
In addition, following OSHA standards may not fully protect worker health. The American Conference of Governmental Industrial Hygienists ACGIH has developed voluntary guidelines for exposure to toxic airborne particulates based on the latest scientific evidence of harm.

Dust and Fume Collection Challenges in the Structural Steel Fabrication Industry Fabricators working with structural steel face a number of challenges when it comes to indoor air quality. Structural steel fabrication often depends on a lot of manual welding. Welding structural steel produces toxic weld fumes that put employee health at risk. In particular, alloys used for structural steel, as well as welding consumables, are usually high in manganese, putting workers at risk for manganism or other nervous system disorders.
Depending on the exact composition of the structural steel alloy, workers may also be exposed to hexavalent chromium, nickel, beryllium or other toxic substances. Exposure to these elements is linked to metal fume fever, lung cancer, kidney disease and other health problems. Cutting and grinding structural steel produces high volumes of dust—especially laser and plasma cutting, commonly used to cut large steel I-beams and girders down to size.
These particulates are irritating the lungs, toxic when inhaled or ingested, and potentially damaging to other equipment and processes. They can also be very challenging to contain and control. Metal dusts created by laser cutting, drilling or grinding of structural steel are combustible.
If they are allowed to accumulate in an enclosed area, they create a serious risk of explosion. Structural steel components that will be exposed to the elements are often treated with corrosion-resistant paints or other treatments to improve their longevity. However, the materials and coatings used to increase corrosion resistance often contain highly toxic elements such as cadmium , which makes working with the dust or fumes even more dangerous.
Structural steel beams and the products made from them are usually very large and heavy. Most structural steel fabricating cannot be contained under a hood. Fabricators may also need to use overhead cranes to move beams and final products around. These factors make source capture, which is usually the most economical and effective method of air quality control, challenging.

How to build a Manufacturing Facility?
From the days of the Industrial Revolution to the newly minted 21st century, the construction of a manufacturing facility has been through its share of changes. Building standards, materials, and equipment have been introduced and improved over years of industrialization and automation. A wide variety of items have been produced from these facilities with new products created every day. But at its heart, a modern manufacturing facility has many of the same considerations as one from the early s.
Да, это. Он - лжец. Он вел себя бесчестно по отношению ко многим людям, и Сьюзан Флетчер - одна из. Он очень о многом ей не сказал - о многих вещах, которых теперь стыдился. Она была его иллюзией, его живой фантазией. Он мечтал о ней по ночам, плакал о ней во сне. Он ничего не мог с собой поделать. Она была блистательна и прекрасна, равной ей он не мог себе даже представить.

И не пытайтесь, коммандер, - прошипел. - Вы рискуете попасть в Сьюзан. Хейл выжидал.
Спокойно. Он оглядел пустой зал. Ни души.
И все-таки, - прервал ее Беккер. Ему в голову пришла другая мысль. - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина. - Тогда вы наверняка ее видели. Это совсем молоденькая девушка. Лет пятнадцати-шестнадцати. Волосы… - Не успев договорить, он понял, что совершил ошибку.

Бринкерхофф кивнул и положил трубку. - Стратмор отрицает, что ТРАНСТЕКСТ бьется над каким-то файлом восемнадцать часов. - Он был крайне со мной любезен, - просияв, сказал Бринкерхофф, довольный тем, что ему удалось остаться в живых после телефонного разговора. - Он заверил меня, что ТРАНСТЕКСТ в полной исправности. Сказал, что он взламывает коды каждые шесть минут и делал это даже пока мы с ним говорили. Поблагодарил меня за то, что я решил позвонить .
Сьюзан отчаянно пыталась встретиться взглядом со Стратмором. Коммандер. Северная Дакота - это Хейл. Но Стратмор смотрел на молодого сотрудника лаборатории систем безопасности. Коммандер спускался по лестнице, ни на мгновение не сводя с него глаз. Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна. - Вы что-то сказали. - Сэр, - задыхаясь проговорил Чатрукьян.
- ТРАНСТЕКСТ вышел из строя. - Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать.
Он поднял вверх голову, надеясь увидеть Гиральду, но окружившие его со всех сторон стены были так высоки, что ему не удалось увидеть ничего, кроме тоненькой полоски начинающего светлеть неба. Беккер подумал, где может быть человек в очках в тонкой металлической оправе.
- Все становится на свои места. Какой-то миг еще ощущались сомнения, казалось, что в любую секунду все снова начнет разваливаться на части.
- Меня не интересует ваша колонка. Я из канадского консульства.
Мидж подтвердила свои слова коротким кивком. - У них нет света.
