Multiple Cell structures
Multiple cell structures  refer to monopole tower with every function accessories such as antenna, boom, dish and other accessories. 

MEGATRO mainly provide fabrication and design of  this multiple cell structures for our overseas clients. This type structure foundation adopt anchor bolts connect with structure base plate and stub legs. Structure foundation belongs to precast concrete foundation with template and anchor bolts underground. And this structure was made of hollow pipe, which can be quickly deployed with minimal hardware and labor, factory drilled to customer specifications or modified in the field, if required, using a carbide-tip bit. In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, GR65, Q235B, Q345B, S355JO, S355JR, ST37, ST52, BS 50B or other.

Our  multiple cell structures often adopt  with some type as follow:

(1) Flange connection
(2) Slip joint
(2) Step type
(3) Stagger type
(4) Others

Pole foundation types have:

Direct embedment
Anchor bolt
Based plate
Vibratory steel caisson

MEGATRO provide multiple cell structures at a much lower material cost than self supporting towers due to the efficient use of steel guy lines.

Since 2004, MEGATRO has been manufacturing every type of multiple cell structures for telecom applications. MEGATRO pioneered the development of transmission tower, telecom tower, substation, and other steel structure and was also at the forefront in the design of Transmission tower. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software.

MEGATRO is one of the few manufactures who assemble a face of multiple cell structures. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies. MEGATRO multiple cell structures systems can accommodate a variety of telecom antenna with mounts. After fabrication multiple cell structures are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers. Even we take secondary finish for client again, which as duplex surface treatment.
