High-strength bolts are made of high-strength or tempered alloy steel and are used where extremely high tensile strength is needed, such as bridges, rails, and high-pressure equipment. They are tightened or released by applying torque to a nut and are commonly used in structural bolting. The tensile materials used in these bolts tend to increase their strength by 25% to 50%. We manufacture the material from Property Class 3.6 to 12.9 with lengths up to 4 meters. The relevant accessories are also designed, manufactured, and supplied.

The importance of architectural bars in the design and construction of buildings, whether for structural or aesthetic purposes, lies in their capability to support tension and compression. Such bars can be fashioned with materials such as concrete and steel. They are custom-made to suit any project and serve in Bridges and structures such as residential & commercial regions. With the capability to offer local production backed by Anker Schroeder's Quality Control Systems, we are committed to serve the Indian Market with minimal lead time and optimised delivered cost.

HSFG bolts, or High Strength Friction Grip bolts, are engineered fasteners that play a vital role in modern structural steel connections. These specialized bolts are meticulously designed to deliver secure, slip-resistant joints by applying a high preload during installation. The resulting friction between the connected surfaces is crucial for preventing any movement under dynamic and high-stress conditions, thereby ensuring the stability and long-term integrity of critical infrastructure projects. Manufactured using high-grade steel, HSFG bolts are known for their exceptional tensile strength and durability. The precise application of preload, achieved by tightening the bolt to a specified torque, generates the necessary clamping force. This force not only enhances the frictional grip but also distributes the load evenly across the joint, which is essential for maintaining structural performance. Such characteristics make HSFG bolts ideal for use in applications such as bridges, high-rise buildings, power plants, and other heavy civil constructions. Furthermore, the unique design of HSFG bolts minimizes the risk of loosening even under repetitive loading and vibrations, which are common in large-scale engineering projects. Their reliable performance reduces the need for additional fastening elements, contributing to more efficient construction practices and lower maintenance requirements over the life of the structure. In addition to their mechanical advantages, HSFG bolts are also favored for their ease of installation and ability to meet stringent safety standards. As construction projects continue to evolve, the demand for high-performance, dependable fastening solutions like HSFG bolts is on the rise. They are an indispensable component in ensuring that modern infrastructures are both safe and resilient, capable of withstanding the challenges posed by dynamic loads and harsh environmental conditions. HSFG bolts exemplify modern engineering precision and are indispensable in both new construction and retrofit projects. Their reliability and superior performance have made them the fastening solution of choice for engineers worldwide, ensuring safety and longevity in every structure consistently.

Conical defense systems, generally with sealed, closed shields, ensure excellent performance quality, stability and long lifespan . The truncated conical fenders accept a very large angle of approach, high resistance to shear.

Cone fenders are designed to perform with closed steel panels, and give efficiency with important berthing and shear angle.

Very well known in Spain and Northern Europe, cellular defenses are available in all sizes and are interchangeable with many older brands. They are ideal when the required hull pressure is low. Cellular defenses support large docking shields.

Well known in Spain and North Europe, Cell fenders are available in all dimensions. Cell fenders are designed to accept large closed steel panels, with high deformation capacity. Can replace old brands easily, same flange for fixings

Trapezoidal fenders are simple but robust ; they equip a wide variety of docks without any problems even under the worst conditions . They are made from a single piece. Trapezoidal DA fenders traditionally have a rubber face and are easy to install.

Cylindrical defenses have a progressive reaction , thanks to their simple and economical design , they benefit from a wide range of dimensions. Simple to install , cylindrical fenders require little maintenance. Widely used in the Mediterranean, they reliably perform their function with chains (up to Ø600mm), central bars (up to Ø1600mm) or special supports for large dimensions. Available from Ø150-75 up to Ø2800-1400

Designed for temporary installations , pneumatic fenders can also be used in ship-to-ship operations, that is, between two ships for the transfer of oil, for example. These pneumatic fenders can also be equipped with chain netting from old tires for greater protection.

Airbags are designed for launching ships; their manufacture meets very precise and strict standards.

Our partner's foam fenders are made from closed-cell polyethylene foam coated with a reinforced polyurethane elastomer. The foam absorbs the energy of docking while the coating resists impacts and wear. The foam fenders are unsinkable and can also be reinforced with chain netting and used tires.

Used in dry docks, lock entrances or canals, rotating fenders serve to guide ships, while absorbing significant berthing energy. Installed in single or double configurations, these defense systems are very flexible.

Roller fenders are dedicated for channel entrances, gates, shipyards, and corners. Singles or twins, roller fenders have a strong energy absorption capacity; soft and gentle contact faces.

DR fenders are a new type of fender developed from D fenders; the rubber-coated steel plate allows the fender to be fixed directly to the structure.

DR Rubber Fenders is a new type of rubber fender developed from D type fender, it enlarge fender bottom width to get embedded steel frame plate inside and to be fixed to the port structure with double row bolts, therefore it get stronger installation strength and longer service life than D type fender.

Extruded fenders are simply made of rubber and can be fixed by a central flat iron or by side angles and bolts. Extrusion allows for the production of defenses of varying lengths which can then be cut and drilled as needed. Pre-tailored cuts and specific sizes are available upon request. Generally black in color, extruded tusks are also available in grey or cream (optional). DD D-shaped defenses , fixed by a flat iron that passes through the defense. DC D-shaped fenders , secured by flat lateral bars connected by bolts. (tugs – pleasure craft – dock ladder protection). SD Square-shaped defenses , fixed by a flat iron that passes through the defense.

Made in Germany, this defense is not made of rubber, but composed of polyurethane elements, in Yellow, Orange or Black color, these defenses have different performance levels.

Shock-absorbing rollers are flexible guides for pontoons and floating structures; a rubber element encasing two steel plates for fixing is added to the rubber bearing. There is no maintenance required for the bearings which are made of plastic and stainless steel.

Tugboat fenders are used for pushing or working as a lateral belt interface.

Tug fenders are often used as the primary pushing fenders on the bow or stern of tugs, but are equally good for pushing flat-sided vessels. Tug fender can be fixed on the hull by the chain or straps, ease of installation. Tapered ends are also available.
