Guardrails are used for safety and barrier purposes and are an integral part of various industrial structures. These assemblies are typically installed at platform ends and are incorporated within mezzanine structures in industrial sites, such as warehouses. They are used on highways as a protection barrier against vehicle impact, to prevent falls, and in production areas. Standard guardrail fabrication materials include variations of Stainless Steel, a material recommended because of its durability. Wooden guardrails are another common barrier material. There are numerous variations of standard guardrails, which must comply with OSHA standards. Both single and double railing systems are a standard guardrail installation option.

Guardrail Types and Styles

The most common types of guardrails include:

W-beam

Curved

Bolt-on

Drop-in

Video on the Types of Guardrails

W-beams

W-beams are the standard traffic and highway safety rails and are constructed in high gauge steel. To protect against environmental conditions, this type of beam is fabricated with zinc coatings and weather (resistant) coated materials.

Curved

Curved guardrails feature a convex or concave-shaped rail and are used to provide protection on roadways and highways that have a bend radius to them. These units are usually prefabricated to fit the required dimensions of the site where they will be installed. Concave rails are those in which the rail curves in towards the vehicle, while convex rails are those that curve away from the vehicle.

Drop-in rails

Drop-in rails feature brackets that allow post sections to slide into the structure upon installation. This type of railing is easily accessible. 

Bolt-on rails

Bolt-on rails involve specific installation with hand tools and drills, though the hardware for this type of railing is typically included by the manufacturer. Single, double, or triple rails may be selected for an application.

Standard Guardrail Applications

Pedestrian walkway protection  

Workstation and transformer area barrier

Protect equipment from forklift damages

Protect building from damage (ie, walls and doors)

Installed along roadways to prevent and minimize accidents

Guardrail Components

A standard guardrail system is mounted to the floor by base plates, which are fastened with anchor bolts. Each guardrail system also includes columns that are commonly fabricated from steel. Such columns, or posts, are often pre-drilled by the manufacturer and include the hardware for installation. Standard galvanized steel systems (specifically 12-gauge) provide durability and are often fabricated in curved, 90-degree variations, for traffic areas. Other variations include cylindrical steel beams and flatter beams, featuring ribbing. For indoor and outdoor areas, railings are typically painted OSHA yellow. The type and amount of beam railing vary according to the application requirements. For instance, the railing can consist of one to three beams and the beams may be coated with UV resistant polyurethane sleeves.

Box Beam Guardrail- Best Choice for Beautiful Surroundings

Box beam guardrail, a kind of highway barrier, is not as common as traditional w beam or thrie beam guardrails, but it caters the need of appreciation of the beauty and is widely used not only on highways, but also in parks, picturesque bridges, etc.

The same as W-beam guardrails, it is made of high quality steel and plated with superior zinc coating or coated with PVC coating. Thereby, it is anti-rust and durable enough to endure the impact force. Additionally, there is no need of paying much money on the maintenance of the box beam guardrail, which makes it cost effectively in the long run.

Box beam guardrails can be used on bridges.

Advantages:

Anti-rust

Corrosion-resistant

Durable and well-constructed

Designed to have a long service life

Can be used with or without blocks

Easy to install and repair

No need of maintenance

W Beam Guard Rails for Highway Collision Safety

W Metal Beam Guard Rails for Highway and Bridges

w-beam guardrail has a section or profile of W shape, it is also named as two wave beam guardrail. This is the major type of beam barriers for highways safety with symmetrical designs on each side of the beam. We supply two kinds of finishes for w beam guardrail panels: hot dipped zinc coating or plastic coating. According to the fabricated shapes, our W-beam guardrails can be divided into two types: the straight line w-beam,or the curved beams.

How to choose straight W beam or Curved Beam used for your uses?
The straight W-beam guardrail can be lined up for transitioning smoothly and is suitable to the curves with a radius greater than 45m. For the radius less than 45m, the pre-curved W-beam guardrail product exploits its advantages to a full.

W beam guard railings can be used in expressway and highways to absorb maximum energy of the impact force when collision occures and reduce harms to cars and people. It can also protect the vehicles against skidding off roads, especially mountain roads and bridges and prevent the pedestrians from the danger of walking across highways.

امنیت در هنگام رانندگی روی جاده‌ها یا پل‌ها اولویت دارد. گارد ریل‌ها ما را در حین تصادفات امن می‌سازند. اما بهترین گارد ریل برای جاهایی مثل جاده‌ها، پل‌ها یا مناطق کاری کدام است؟ XZL ROADSafety آماده کمک به شما در نظرگیری گارد ریل‌هاست.

نکات ساده‌ای که باید به خاطر داشته باشید هنگام انتخاب سیستم‌های گارد ریل برای جاده‌ها و پل‌ها

هنگام انتخاب دیوارهای محافظ برای جاده‌ها و پل‌ها، چند نکته باید در نظر گرفته شود. اول اینکه باید فکر کنید دیواره محافظ کجاستفاده می‌شود. آیا این دیواره در جاده‌ای است که ماشین‌های سرعت زیاد دارند یا روی پلی که کامیون‌های بزرگ عبور می‌دهند؟ طبیعت ترافیک هم به تعیین اینکه دیواره محافظ باید چقدر قوی باشد، کمک می‌کند.

حالا فکر کنید دیواره محافظ از چه ماده‌ای ساخته شده است. دیواره‌های محافظ فولادی سخت هستند و دیواره‌های محافظ چوبی انعطاف‌پذیر هستند. همچنین باید به آب و هوای محلی نیز توجه کنید. اگر انتظار دارید باران زیادی برسد، شاید دیواره محافظی که بتواند با آب و هوای سخت زمستان مقابله کند، لازم باشد.

دلیل اهمیت انتخاب درست دیواره محافظ برای مناطق کاری

مناطق کاری جاهایی هستند که ساخت یا تعمیر جاده در آنجا اتفاق می‌افتد. موضوعات زیادی وجود دارد که باید به آن توجه کنیم، اما انتخاب درست دیواره محافظ برای حفاظت از کارگران و رانندگان خیلی مهم است. دیواره محافظ باید قوی genough باشد تا ضربات ماشین‌های عبوری را جذب کند.

انتخاب درست دیواره محافظ برای مناطق کاری می‌تواند تصادفات را جلوگیری کند و زندگی‌ها را نجات دهد. XZL ROADSafety توصیه می‌کند انتخاب کنید دیوارهای حفاظتی ترافیکی که نصب و نگهداری آنها ساده است و همه را در منطقه کاری ایمن می‌سازد.

نکات برای ارزیابی سیستم‌های دیواره محافظ بر اساس قوی بودن و طول عمر

برای اطمینان از ایمنی و طول عمر دیواره‌های محافظ، باید به این نکات دقت کنید. ابتدا، نظرات تست تصادف را در نظر بگیرید لوازم جانبی نرده محافظ . امتیاز بالاتر در صورت وقوع تصادف حمایت بیشتری فراهم می‌آورد

دوم، توجه کنید که چقدر دیواره محافظ نیاز به نگهداری دارد. برخی از دیواره‌ها ممکن است به راحتی قابل تعمیر باشند، در حالی که دیگران نیاز به تعمیر گسترده دارند. دیواره محافظی را انتخاب کنید که بهترین جوابگوی نیازها و بودجه شما باشد.

ویژگی‌های چراغ‌های امنیتی خوب

چراغ‌های امنیتی خوب چند ویژگی دارند که آنها را متمایز می‌کند. برای مدل‌هایی با ساختار محکم انتخاب کنید سوراخ امنیت جاده ساخته شده از مواد قوی مانند فولاد زنگاله‌ای یا آلومینیوم. این مواد می‌توانند آب و هواهای سخت را تحمل کنند.

چراغ‌های امنیتی با کیفیت باید نشانگرهای بازتابی داشته باشند تا بینایی شب را افزایش دهند. این بینایی به رانندگان فرصت می‌دهد تا چراغ امنیتی را ببینند و عمل جلوگیری انجام دهند. XZL ROADSafety پیشنهاد می‌کند که چراغ‌های امنیتی استفاده شده، پوشش ضد زنگ زدگی داشته باشند تا مدتی طولانی‌تر بمانند.

کدام طراحی چراغ امنیتی بیشترین حمایت را ارائه می‌دهد؟

هنگامی که به گزینه‌های مختلف سیستم‌های دیواره محافظت می‌پردازید، فکر کنید که در هر موقعیت خاص نیاز به چه چیزی دارید. برای جاده‌ها، شما ممکن است نیاز به یک دیواره محافظت داشته باشید که بتواند تأثیر را جذب کند و وسایل نقلیه را به صورت امن بازنشانی کند. یک دیواره محافظت باید قوی‌تر و مقاوم‌تر باشد.

هنگامی که به مناطق کاری اشاره می‌کنیم، دیواره‌های محافظتی که نصب و نگهداری آسانی دارند بهتر عمل می‌کنند. برای مقایسه طراحی‌های دیواره محافظت بین شرکت‌ها جستجو کنید تا بهترین تناسب ممکن برای نیازهای خاص خود را پیدا کنید. XZL ROADSafety انواع مختلفی دارد تا بتواند با طراحی دیواره محافظت، حفظ ایمنی همه را به حداکثر برساند.
