Transmission Poles
The unique Yunmei Poles manufacturing process creates hollow, steel-reinforced concrete poles of great strength and relatively light weight, by spinning the mould at high speed.
Products
Yunmei company specialized in the production of steel transmission poles 35-220kV and is an excellent supplier of State Grid Worldwide.
Our Power Starts With You
Every line is unique. That means trust, experience and dependability become as important as design, manufacturing and delivery. From steel tapered and H-frames, to concrete and patented steel/concrete hybrid poles, our industry-leading engineering team can create custom power transmission poles designed especially for your line. We back our designs with real-world testing to ensure we create the most reliable transmission pole for you. We design manufacture and coat steel, concrete, and hybrid transmission poles to support any voltage class. Backed by over four decades of experience and a global network of manufacturing facilities, Valmont Utility can offer you:
Any design of your choice
This enables customization of any line segment with structures that are optimized for the environment and creating a line that is more cost effective.
The Newmark® Standard of Excellence
Newmark transmission towers offer the versatility and light weight of steel, the low maintenance and durability of concrete (spun and static cast).
Exceptional Ease of Installation
When compared to other types of structures, the speed and ease of installation, concrete and hybrid poles increases its value in construction cost savings.
Uniform Material Strength
Steel and concrete offer uniform material strength throughout the entire structure, providing more consistency and predictability than wood.
Our Factory
Our own metallurgical lab
TAPP`s in-house metallurgical lab ensures consistet high quality steel. TAPP performs a Chemical composition test. Mechanical properties test, and Charpy V-notch test with all steel coils.
iso 9001:2008 sertified
TAPP`s ISO 9001 program quarantees that products and services consistently meet customer`s requirements and that quality is continuously improving.
every type of steel. delivered.
TAPP can fabricate products from nearly any type of steel required including: ASTM A572, A588, A871, A36, A588, A501, A500, AA53 and many more.
best lead times
Whith over $30m of pre-purchased raw material on hand, combied whith highly automated machinery, TAPP can offer extremely competitive lead times on any project.
More than 20 years of experience, numerous awards and certificates
Our factory now covers an area of 287,000 square meters
Including 36 senior technical and economic personnel
Every year the output is 80000-100000 tons
The equipment we use helps us with these 4 steps of the process significantly.
For example, the 3200T double linkage electro-hydraulic synchronous CNC bending machine can produce elbows and bends from plate, which are 35mm thick and 12.5 m long and match the requirements of polygonal towers. And CNC flame and plasma cutting machines make sure that the processing and assembly of the parts is as precise as it can ever be.
OUR STEEL IS LIKE A SUPERHERO
Weathering steel is a self-healing, maintenance-free and corrosive resistant steel that will fight against whatever Mother Nature has up her sleeve.
CUSTOMER-ORIENTED PRODUCTS
When we work on a design or a specific tower, we always make sure that the client’s needs are met first.
INSPECTION & TESTING
Our Quality Assurance team of professional inspectors check every section for proper welds to ensure they meet our clients’ demands for each case.
IT WILL DEFINITELY WORK
Before shipping our products to their destination, our QA team pre-fits the structures to eliminate the possibility of failure during assembly on site.
YOU CAN TRUST US. WE ARE VERY THOROUGH
All kinds of tests and checks can be performed to make sure the parts and structures work as they are supposed to.
Our manufacturing process includes:
Step one:
Finding the right parts/details — once a design option is approved, we use 3D detailing to decide what joints, bolts and nuts, plate sizes to use, where assembly and construction points should be. It also determines Bill of Materials, as well as Erection and Shop Drawings, minimizing human error.
Step two:
Assembling the prototype — before going into mass production, we assemble every new tower type to see if the design works.
Step three:
We produce a batch of towers/poles and when it’s done conduct on-site testing — every new tower type is assembled in the field, calibrated, rigged and tested to make sure it matches the client’s specifications.
Step four:
When the batch is ready, we label the product and pack it before shipping to its destination.
Packing and Delivery
WE ALWAYS DELIVER WHEN
WE SAY WE WILL
Our reputation is not just about the quality of product or it’s appearance but the fact of delivering the work in time. And in the fifteen years of making steel structures, we have managed to do it in time in 99% of cases. The remaining 1% of delays was mostly related to weather conditions and other factors we had no control over.
DIVERSIFIED
TRANSPORTATION
Sometimes, nature or circumstance interfere with our plans so to ensure that our steel structures are always delivered in time to their destination, we have created a diversified portfolio of transportation providers to always find a way even when it seems there isn’t one.
ON SITE
ADJUSTMENTS
Even with the best specialists in their fields, the best parts and all the testing and experience, sometimes these precautions are not enough and our products require last minute fixes on site. We make sure to provide such assistance in every such case for every such client.
We have the experience of delivering our steel structures via different transportation means: auto, railroad and by sea in a container. Regardless of the method of delivery, we guarantee that your cargo will be safe while it’s being shipped to you. We try and minimize the number of places the product goes, by combining the parts of structures in as few packages as possible. This speeds up the loading and unloading process too. All the small details such as bolts, screws, washers and plates are securely packed in steel barrels to minimize the risk of loss of details upon delivery.
